Lars Hofhansl commented on HBASE-7205: -------------------------------------- Looking at HBASE-6308 it seems the memory behavior didn't change principally. If this is indeed a new problem I will make this a blocker and sink the current 0.94.3RC for this. Any patch here should also explore the memory behavior in a test (although I am not entirely sure how one would do that) > 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: 0.92.2, 0.94.2 > Reporter: Adrian Muraru > Priority: Critical > Fix For: 0.96.0, 0.94.4 > > > 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 regions of a table in each HRS. -- This message is automatically generated by JIRA.
