Apache Sqoop Known Issues

Sqoop 1

— Hive, Pig, and Sqoop 1 fail in MRv1 tarball installation because /usr/bin/hbase sets HADOOP_MAPRED_HOME to MR2

This problem affects tarball installations only.

Bug: None

Severity: High

Resolution: Use workaround.

Workaround: If you are using MRv1, edit the following line in /etc/default/hadoop from
export HADOOP_MAPRED_HOME=/usr/lib/hadoop-mapreduce
to
export HADOOP_MAPRED_HOME=/usr/lib/hadoop-0.20-mapreduce

In addition, /usr/lib/hadoop-mapreduce must not exist in HADOOP_CLASSPATH.
