Subject [jira] [Created] (HBASE-7205) Coprocessor classloader is replicated for all regions in the HRegionServer
Date Wed, 21 Nov 2012 23:42:58 GMT
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.
