Apache Pig Known Issues
— Hive, Pig, and Sqoop 1 fail in MRv1 tarball installation because /usr/bin/hbase sets HADOOP_MAPRED_HOME to MRv2
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.
Pig fails to read Parquet file (created with Hive) with a complex field if schema not specified explicitly
Bug: None
Severity: Low
Workaround: Provide the schema of the fields in the LOAD statement.
