Subject Re: copyTable mapreduce job failing with ScannerTimeoutException
Date Fri, 16 Sep 2016 14:51:47 GMT
Looking at the regionserver's log reported as TooBusy, I always see these
periodic Memflushes to free WAL, up to 5 min before the final failure, for
various tables' columns. So I think those must be causing excessive flushes
that regionserver can't keep up with.

I was looking for a parameter to increase # of retries, which is set to 5:
client.AsyncProcess: #18, table=3079_01, attempt=5/4 failed=1ops, last
exception: org.apache.hadoop.hbase.RegionTooBusyException

But don't see any property that would do that.
