org.apache.sqoop.submission.mapreduce.MapreduceSubmissionEngine.initialize(MapreduceSubmissionEngine.java:93) Error

Setting up sqoop on my testing environment and got this error

"org.apache.sqoop.submission.mapreduce.MapreduceSubmissionEngine.initialize(MapreduceSubmissionEngine.java:93)"

No idea at first, very hard to find this was the cause. But clean $SQOOPBASE/server/logs/localhost.[date].log helps to clarify the problem.

In the newly generated file. I see the following error. It is clear the sqoop apps failed to find mapreduce setting. Checked the $SQOOPBASE/server/conf/sqoop.properties file and found the parameter "org.apache.sqoop.submission.engine.mapreduce.configuration.directory" is set to default."/etc/hadoop/conf". Replaced this with the correct hadoop installation directory then restart server. The error is gone.
