Subject [jira] [Commented] (HBASE-9374) Client requires write access to hbase.local.dir unnecessarily
Date Thu, 29 Aug 2013 00:05:53 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753069#comment-13753069
] 

Nick Dimiduk commented on HBASE-9374:
-------------------------------------

While this change is being made, TestProtobufUtil should be moved into hbase-client so that
its location is consistent with ProtobufUtil.

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