> loadIncrementalHFiles sometimes throws FileNotFoundException on retry
> ---------------------------------------------------------------------
>
> Key: HBASE-21183
> URL: https://issues.apache.org/jira/browse/HBASE-21183
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.2.0
> Reporter: Tim Robertson
> Priority: Major
>
> On a nightly batch job which prepares 100s of well balanced HFiles at around
> 2GB each, we see sporadic failures in a bulk load.
> I'm unable to paste the logs here (different network) but they show e.g. the
> following on a failing day:
> {code:java}
> Trying to load hfile... /my/input/path/...
> Attempt to bulk load region containing ... failed. This is recoverable and
> will be retried
> Attempt to bulk load region containing ... failed. This is recoverable and
> will be retried
> Attempt to bulk load region containing ... failed. This is recoverable and
> will be retried
> Split occurred while grouping HFiles, retry attempt 1 with 3 files remaining
> to group or split
> Trying to load hfile...
> IOException during splitting
> java.io.FileNotFoundException: File does not exist: /my/input/path/...
> {code}
> The exception get's thrown from [this
> line|https://github.com/apache/hbase/blob/branch-1.2/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/LoadIncrementalHFiles.java#L685].
>
> I should note that this is a secure cluster (CDH 5.12.x).
> I've tried to go through the code, and don't spot an obvious race condition.
> I don't spot any changes related to this for the later 1.x versions so
> presume this exists in 1.5.
> I'm yet to get access to the NameNode audit logs when this occurs to trace
> through the rename() calls around these particular files.
> I don't see timeouts like HBASE-4030
