Gabor Bota updated HADOOP-15604:
--------------------------------
Description:
Confirm that the I/O thresholds are the reason for unprocessed items in
DynamoDB metadata store
There's ~50 files being committed; each in their own thread from the commit
pool; assume the DDB repo is being overloaded just from one single process
doing task commit. We should be backing off more, especially given that failing
on a write could potentially leave the store inconsistent with the FS (renames,
etc)
