Added a new patch. I have tested this patch also. Thanks for the review
[~jarcec]. Very much appreciated.
> HADOOP_MAPRED_HOME should be defaulted correctly
> ------------------------------------------------
>
> Key: SQOOP-1260
> URL: https://issues.apache.org/jira/browse/SQOOP-1260
> Project: Sqoop
> Issue Type: Bug
> Environment: Hadoop 2.x
> Reporter: Venkat Ranganathan
> Assignee: Venkat Ranganathan
> Attachments: SQOOP-1260-2.patch, SQOOP-1260.patch

>
> When running Sqoop on Hadoop 2.x which has been installed using the BigTop
> layout (with a custom hadoop-layout.sh), we run into issues in a setup where
> only Hadoop and sqoop are installed with the failure in the compilation of
> the generated Java file.
> This is because in Sqoop, the HADOOP_MAPRED_HOME is defaulted to HADOOP_HOME
> (/usr/lib/hadoop by default) when the variable is not set.
> This results in the mapreduce libraries not being added to the classpath and
> hence the failure. If we have HBase installed, then we add the HBase
> classpath which causes the mapreduce libraries to be brought into the
> classpath and hence we don't see the issue.
> We should default HADOOP_MAPRED_HOME to /usr/lib/hadoop-mapreduce (the BigTop
> default) if the directory is present else default to HADOOP_HOME
