Adrian Muraru created HBASE-7205:
------------------------------------
Summary: Coprocessor classloader is replicated for all regions in
the HRegionServer
Key: HBASE-7205
URL: https://issues.apache.org/jira/browse/HBASE-7205
Project: HBase
Issue Type: Bug
Components: Coprocessors
Affects Versions: 0.94.2, 0.92.2
Reporter: Adrian Muraru
HBASE-6308 introduced a new custom CoprocessorClassLoader to load the
coprocessor classes and a new instance of this CL is created for each single
HRegion opened. This leads to OOME-PermGen when the number of regions go above
hundres / region server.
Having the table coprocessor jailed in a separate classloader is good however
we should create only one for all table regions in each HRS.
