I searched a lot but failed to find a solution, could you please give your advice on it?
Thanks!

This particular class
oracle.adfinternal.view.faces.taglib.region.RichDeclarativeComponentTag
is part of the ADF Faces Runtime 11 library. Add it up to your project.
Also Make sure to add
javax.faces.context.ExternalContext
class , which is part of the Java EE 1.5 API library.
Also add JSF 1.2 library to your project.

Cannot setup Apache Spark 2.1.1 on Windows 10

I have installed Apache Spark 2.1.1 on Windows 10, with Java 1.8 and Python version 3.6 Anaconda 4.3.1. I have also downloaded the winutils.exe and setup environment avriables for JAVA_HOME, HADOOP_HOME and SPARK_HOME as well as updated the path variable. I have also run winutils.exe chmod -R 777 \tmp\hive. But I am getting the below error when running pyspark in cmd prompt.
Please please can someone help, let me know if I missed out any important detail
Thanks in advance!

Welcome to

Setup that worked for me is as follows "i didn't use winutils.exe":-
install pyspark and findspark using "Anaconda Command Prompt" as
pip3 install pyspark
and
pip3 install findspark
as you have already downloaded spark setup. unzip it and keep it in "C" drive i.e. "C:\spark-2.2.0-bin-hadoop2.7" and create new environment variable "SPARK_HOME" and set it to "C:\spark-2.2.0-bin-hadoop2.7\bin" and open "path" variable in system variables and add the same there as well.
now open your command prompt and come from "C:\User*" to "C:\" by doing cd.. twice and run following command
set SPARK_HOME='spark-2.2.0-bin-hadoop2.7'
and you are good to go.
Now you just have to import the file location before importing pyspark in your jupyter notebook. use following code:-
import findspark
findspark.init('C:\spark-2.2.0-bin-hadoop2.7')
import pyspark

ClassNotFoundException is thrown when running ExportSnapshot

I'm getting a confusing ClassNotFoundException when I try to run ExportSnapshot from my HBase master node. hbase shell and other commands work just fine, and my cluster is fully operational.
This feels like a Classpath issue, but I don't know what I'm missing.

Problem
It turns out this is because the mapreduce2 JARs are not available in the classpath. The classpath was properly set up, but I did not have the mapreduce2 client installed on that node. HBase's ExportSnapshot apparently depends on those client JARs when exporting snapshots to another cluster because it writes to HDFS.
Fix
If you use Ambari:
Load Ambari UI
Pull up node where you were running the ExportSnapshot from and getting the above error
Under "components", click "Add"
Click "Mapreduce 2 client"
Background
There's a ticket here https://issues.apache.org/jira/browse/HBASE-9687 where the title is ClassNotFoundException is thrown when ExportSnapshot runs against hadoop cluster where HBase is not installed on the same node as resourcemanager. The title implies that installing resource manager is the fix and this may work; however, the crux is you need the hadoop mapreduce2 jars in the classpath and you can do that by simply installing the mapreduce2 client.
For us, specifically, the reason our snapshot exports were working one day and broken the next is that our HBase master switched on us b/c of another issue we had. Our backup HBase master did not have the mapreduce2 client JARs, but the original primary master did.

Hive startup -[ERROR] Terminal initialization failed; falling back to unsupported

I have downloaded hive and modified HADOOP_HOME to
HADOOP_HOME=${bin}/../../usr/local/hadoop
my actual hadoop path is
/usr/local/hadoop
in .bashrc i have added the below env variables
export HIVE_HOME=/usr/lib/hive/apache-hive-1.1.0-bin
export PATH=$PATH:$HIVE_HOME/bin
export CLASSPATH=$CLASSPATH:/usr/local/Hadoop/lib/*:.
export CLASSPATH=$CLASSPATH:/usr/local/hive/lib/*:.
then i tried starting hive using bin/hive. I got the below error

I had the same problem and got it working from this link:
https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started
Hive has upgraded to Jline2 but jline 0.9x exists in the Hadoop lib.
So you should follow these steps:
Delete jline from the Hadoop lib directory (it's only pulled in transitively from ZooKeeper).
export HADOOP_USER_CLASSPATH_FIRST=true

Try after removing the jline-0.9.94.jar file under the path $HADOOP_HOME/share/hadoop/yarn/lib/jline-0.9.94.jar
Here's the link to jira ticket
https://issues.apache.org/jira/browse/HIVE-8609

I just set the
HADOOP_USER_CLASSPATH_FIRST=true
and it works for me for this issue.

Try to delete one of this file
SLF4J: Found binding in [jar:file:/usr/local/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/lib/hive/apache-hive-1.1.0-bin/lib/hive-jdbc-1.1.0-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class]
then i think it will only choose to bind to one. so multiple binding will not be available anymore

I had the same problem with cloudera CDH5.4 . Removing jline-0.9.94.jar from yarn/libs folder worked for me.

With Hadoop version 2.4.1 and Hive 1.2.0. I had the same issue. And after setting HADOOP_USER_CLASSPATH_FIRST=true in .bashrc
It worked like a charm!!!

Do this locate jline.
The file, jline-0.9.94.jar, is located in 3 locations, delete it from all the 3 locations and do the necessary export:
$ export HADOOP_USER_CLASSPATH_FIRST=true

With the new version of Hive (1.2.1), I just had to replace jline-2.12.jar with jline-2.13.jar in the installation / lib folder.

check this link it might help you Facing issue while running hive from CLI

You should init the hadoop libary:
$ vi ~/.bashrc
$ export HADOOP_USER_CLASSPATH_FIRST=true
$ source .bashrc
$ hive

I renamed
addJava "-Djline.terminal=jline.UnixTerminal"
to
addJava "-Djline.terminal=jline2.UnixTerminal"
in the "activator" file

Upgrading your JavaFX runtime to at least 2.1 will fix your problem.
The sample source you reference is designed for a 2.1 runtime, not a 2.0 runtime.
The reason the new source is incompatible with 2.0 is that 2.1 adds an inherited #DefaultProperty annotation to the Pane class (this annotated behaviour gets inherited by GridPane). Because of this, when you write fxml using 2.1 you can omit certain tags which get defaulted, making the 2.1 fxml less verbose than what is required for 2.0. A full explanation of this is provided by Dustin Marx in his blog.

Upgrade from JavaFx 2.0 to JavaFx 2.2 will fix this problem.
