I have a needle-in-the-haystack type scan. I have tried to read all the
issues with ScannerTimeoutException and LeaseException, but do have not
seen anyone report what I am seeing.
Running 0.92.1-cdh4.1.1. All config wrt to timeouts and periods are
default: 60s.
When I run a scanner that will return few results and my cache setting
is a bit too high for results to return in 60 seconds, i sometimes get a
subset of results (the last few returnable rows) and no exception. it
may take a while to get those results. Other times I get the
LeaseException, the ScannerTimeoutException, or the
RetriesExhaustedException. I can see throwExceptionIfCallerDisconnected
in RS logs.
The incorrect return set has me very concerned. I can easily reproduce
this with my own code or hbase shell.
Any help is greatly appreciated.
Cheers,
Randy Fox
