Hi,
I am currently getting TabletServerBatchReaderIterator Java heap space errors.
Below are the log outputs. Do any of you know what is going on and what is
the proper solution to fix this issue?
A little detail on the use case is I have an application which uses a thread
pool that does concurrent queries on Accumulo. Any insight on this issue is
greatly appreciated .
Thanks.
