IndexOutOfBoundsException with Snappy compressed SequenceFile from Flume
Hi all,

   This is my first post to the hive mailing list and I was hoping to get some help with the exception I am getting below.  I am using CDH4.2 (hive 0.10.0) to query snappy compressed, Sequence files that are built using Flume (relevant portion of flume conf below as well).  Note that I'm using a SequenceFile as it was needed for Impala integration.  Has anyone see this error before?  Couple of additional points to help diagnose:

 1.  Queries seem to be able to process some mappers without issues.   In fact, I can do a simple select * from <table> limit 10 without issue. However if I make the limit high enough, it will eventually fail presumably as it needs to read in a file that has this issue.
 2.  The same query runs in Impala without errors but appears to "skip" some data.  I can confirm that the missing data is present via a custom map/reduce job
 3.  I am able to write a map/reduce job that reads through all of the same data without issue and have been unable to identify data corruption
 4.  This is a partitioned table and queries fail that touch ANY of the partitions (and there are hundreds) so this does not appear to be a sporadic, data integrity problem (table definition below)
 5.  We are using '\001' as our field separator.  We are capturing other data also with SequenceFile, snappy but using '|' as our delimiter and we do not have any issues querying there.  Although we are using a different flume source.

My next step for debugging was to disable snappy compression and see if I could query the data.  If not, switch from SequenceFile to simple text.

I appreciate the help!!!
