[jira] [Created] (TRAFODION-3217) Mechanism to drop obsolete cached SPJ library/jar files

Sandhya Sundaresan created TRAFODION-3217:
---------------------------------------------

             Summary: Mechanism to drop obsolete cached SPJ library/jar files 
                 Key: TRAFODION-3217
                 URL: https://issues.apache.org/jira/browse/TRAFODION-3217
             Project: Apache Trafodion
          Issue Type: Bug
          Components: sql-general
    Affects Versions: 2.4
            Reporter: Sandhya Sundaresan


As part of storing UDR libraries in a blob column in metadata, we  extract and store these libraries locally during execution of the UDRs.  When a library is altered or dropped the old cached  copies of the libraries are left over on each node. These need to be detected and cleaned up  on every node.
