Subject [jira] [Commented] (HIVE-6369) ORC Writer (int RLE v2) fails with ArrayIndexOutOfBounds
Date Tue, 04 Feb 2014 21:28:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13891233#comment-13891233
] 

Gopal V commented on HIVE-6369:
-------------------------------

Yes, this is from a recent build.

But to make absolutely sure I disassembled the RLE writer from the built jar

{code}
private void preparePatchedBlob();
  Code:
   0:	lconst_1
   1:	aload_0
   2:	getfield	#142; //Field brBits95p:I
   5:	lshl
   6:	lconst_1
   7:	lsub
   8:	lstore_1
{code}

I can see that the operations are all lshl (long shift left) instead of ishl (integer shift
left).
