             Summary: BulkLoad May Fall Into Unbelievable Retry Attempt in Some case
                 Key: HBASE-24420
                 URL: https://issues.apache.org/jira/browse/HBASE-24420
             Project: HBase
          Issue Type: Bug
            Reporter: wuchang


In https://issues.apache.org/jira/browse/HBASE-14541, the retry logic changed from a configurable retry times(by configuration item hbase.bulkload.retries.number)  to below retry logic to process the issue that the RegionSplit happened during bulk load:
{code:java}
int maxRetries = getConf().getInt("hbase.bulkload.retries.number", 10);
maxRetries = Math.max(maxRetries, startEndKeys.getFirst().length + 1);
if (maxRetries != 0 && count >= maxRetries) {
  throw new IOException("Retry attempted " + count +
    " times without completing, bailing out");
}
{code}
This issue caused another issue in our cluster, that is:

Our table has 2000 regions and our bulk load failed for an configuration issue(unrelated with this case, so ignore the failure reason) and then ,the bulk load fall into a retry disaster and after retry reached about 200, our HDFS crashed for OOM.

During with, the HBase table splits never happened;

I think the patch in HBASE-14541 didn't handle the unrecoverable retry case and in this case(I think many reason may incur unrecoverable retry) the meaningless retry attempts  becomes disaster and is un-configurable because we cannot change the Region number of our table;
