— Hive, Pig, and Sqoop fail in MRv1 tarball installation because /usr/bin/hbase sets HADOOP_MAPRED_HOME to MR2
This problem affects tarball installations only.
Resolution: None; use workaround
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
Workaround: Provide the schema of the fields in the LOAD statement.
