Subject [jira] [Commented] (HBASE-1936) ClassLoader that loads from hdfs; useful adding filters to classpath without having to restart services
Date Mon, 01 Apr 2013 16:53:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13618907#comment-13618907
] 

Jimmy Xiang commented on HBASE-1936:
------------------------------------

I agree.  I will take a look.  I was thinking to reuse some logic in the coprocessor framework.
 The new class loader (most likely the existing one in coprocessor framework, with some refactory),
will be used to load some non-exempt classes (not system classes) from a configurable location,
which could be a local folder, or a HDFS folder.  Ideally, this loader will be used only for
get/scan calls in region server side (besides coprocessor related).
