Subject [jira] [Commented] (STORM-3345) AbstractNonblockingServer$FrameBuffer pool-14-thread-163 [ERROR] Unexpected throwable while invoking!

    [ https://issues.apache.org/jira/browse/STORM-3345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16791890#comment-16791890

Stig Rohde Døssing commented on STORM-3345:
-------------------------------------------

It is basically a nullpointerexception in disguise.

This is the line you're getting the error in https://github.com/apache/storm/blob/v1.2.3/storm-core/src/clj/org/apache/storm/stats.clj#L1338.
Note the call to component-type. The implementation here https://github.com/apache/storm/blob/v1.2.3/storm-core/src/clj/org/apache/storm/stats.clj#L834
can return nil if none of the 3 clauses are true. If it does, you will get the error you see.


The doc for component-type calls out that it can return nil if the component is not fonud,
so the solution is probably to figure out what to do in the condp in line 1338 if the component
is not found.
