----------------------------------------
Summary: GC/OOM during BulkLoad
Key: PHOENIX-2649
URL: https://issues.apache.org/jira/browse/PHOENIX-2649
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.7.0
Environment: Mac OS, Hadoop 2.7.2, HBase 1.1.2
Reporter: Sergey Soldatov
Priority: Critical
Phoenix fails to complete bulk load of 40Mb csv data with GC heap error during
Reduce phase. The problem is in the comparator for TableRowkeyPair. It expects
that the serialized value was written using zero-compressed encoding, but at
least in my case it was written in regular way. So, trying to obtain length for
table name and row key it always get zero and reports that those byte arrays
are equal. As the result, the reducer receives all data produced by mappers in
one reduce call and fails with OOM.
