Hadoop wordcount Pseudodistributed mode error Exit code:127

I have installed Hadoop 2.7.1 stable version. I followed Tom White's book for installation in Pseudodistributed mode. I did set all environment variables like JAVA_HOME, HADOOP_HOME, PATH etc.. I configured yarn-site.xml, hdfs-site.xml, core-site.xml, mapred-site.xml.
I copied the sample file file.txt using following command.
$hadoop fs -copyFromLocal textFiles/file.txt file.txt
which shows me
Found 2 items

RAMAs-MacBook-Pro:hadoop-2.7.1 RAMA$ hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar wordcount file.txt output
it is throwing me following exception, for which I am not able to find any feasible solution.

Any suggestions/comments is of great help...

In hadoop-env.sh, explicitly add the java home path in JAVA_HOME variable.

tachyon0.8.2 deployed with hadoop2.6.0,but the IPC version are not matched

Now,I want to deploy the tachyon0.8.2 on my ubuntu14.04,I already has hadoop and spark:

export TACHYON_MASTER_ADDRESS=${TACHYON_MASTER_ADDRESS:-master}
export TACHYON_UNDERFS_ADDRESS=${TACHYON_UNDERFS_ADDRESS:-hdfs://master:9000}
Then, I run the bin/tachyon formatand bin/tachyon-start.sh local.
I cannot see the tachyonMaster in JPS:

What should I do for this problem?

This exception arises due to version mismatch of Hadoop client and server side. Check your Hadoop version, and then recompile Tachyon against that version using this command:
mvn -Dhadoop.version=your_hadoop_version clean install
Example: mvn -Dhadoop.version=2.4.0 clean install
Now configure your compiled Tachyon and it should work fine. Reference link.

When I went to the Stderr logs as mentioned in the above stack trace, the actual error came out to be
Error: Could not create the Java Virtual Machine.
When I try to increase HADOOP_HEAPSIZE to 1024, the namenode, datanode and yarn daemons do not start at all and give me the same error of could not create java virtual machine
Has someone got the same problem ? How to solve this issue ?

You can solve this problem by editting the file /etc/hadoop/hadoop-env.sh like the one below:
export HADOOP_HEAPSIZE=3072

Anyone can help me please ?
Thanks.

The Cassandra error has nothing to do with OpenJDK, although I do recommend using Oracle's.
You need to make sure you're on a valid upgrade path: http://docs.datastax.com/en/upgrade/doc/upgrade/cassandra/upgradeC_c.html
You can't trivially upgrade from a Cassandra older than 1.2.9 to 2.0, and you can't upgrade from 1.x to 2.1 without first going to 2.0.7 or later.
Suggested upgrade path per documentation: 1.x > 1.2.9 > 2.0.7 > 2.1.x

Your java -version output shows your not using correct JDK. It should be something like below.
Java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)
For this tell the system that there's a new Java version available
$ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_version/bin/java" 1
Set the new JDK as the default using the following command:
$ sudo update-alternatives --config java
You can refer the link https://devopsmanual.in/2018/03/07/how-to-upgrade-datastax-cassandra/ for more details.
