Subject [jira] [Created] (HCATALOG-183) Memory leak in HCat 0.1/0.2
Date Fri, 16 Dec 2011 07:13:30 GMT
Memory leak in HCat 0.1/0.2

                 Key: HCATALOG-183
             Project: HCatalog
          Issue Type: Bug
          Components: metastore
    Affects Versions: 0.2
            Reporter: Mithun Radhakrishnan

When one leaves the HCatalog server running for long (in a secure setup), with requests continuously
coming in, one sees that the memory footprint of the metastore-server increases continuously,
until it culminates in an OutOfMemoryError:

2011-12-01 18:11:00,620 ERROR api.ThriftHiveMetastore$Processor (
- Internal error processing get_partition_names
java.lang.OutOfMemoryError: Java heap space

The OOM is preceded by other failures, including a "GSS initiate failure" (in spite of a client-side
kinit), and an "Error occurred during processing of request".
