Subject [jira] [Commented] (HBASE-14347) Add a switch to DynamicClassLoader to disable it and make that the default
Date Fri, 02 Oct 2015 16:47:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14941372#comment-14941372
] 

Esteban Gutierrez commented on HBASE-14347:
-------------------------------------------

+1 Thanks for working on this one [~huaxiang]. 
[~mbertozzi] would be an option for you to load remotely from the RS or the master those jars?
For a secure environment I think the only requirement would be to have a signed jar.

> Since HBASE-1936 we have the option to load jars dynamically by default from HDFS or
the local filesystem, however hbase.dynamic.jars.dir points to a directory that could be world
writable it potentially opens a security problem in both the client side and the RS. We should
consider to have a switch to enable or disable this option and it should be off by default.
