-----------------------------------

             Summary: Client requires write access to hbase.local.dir unnecessarily
                 Key: HBASE-9374
                 URL: https://issues.apache.org/jira/browse/HBASE-9374
             Project: HBase
          Issue Type: Bug
          Components: Client, Protobufs
    Affects Versions: 0.95.2
            Reporter: Nick Dimiduk


Per this [thread|http://mail-archives.apache.org/mod_mbox/hbase-dev/201308.mbox/%3cCANZa=GuLO0jTLs1fF+5_NRDczO+M=SSqjeAGVEeiCY8injbP8w@mail.gmail.com%3e]
from the dev list.

It appears that as of HBASE-1936, we now require that client applications have write access
to hbase.local.dir. This is because ProtobufUtil instantiates a DyanamicClassLoader as part
of static initialization. This classloader is used for instantiating Comparators, Filters,
and Exceptions.

Client applications do not need to use DynamicClassLoader and so should not require this write
access.
