> LoadTestTool need to have a way to ignore keys which were failed during

> Key: HBASE-9108

> Project: HBase
> Issue Type: Improvement
> Components: test
> Affects Versions: 0.95.0, 0.95.1, 0.94.9, 0.94.10
> Reporter: gautam
> Assignee: gautam
> Priority: Critical

> HBASE-9108.patch._trunk.4, HBASE-9108.patch._trunk.7,
> HBASE-9108.patch._trunk.8
>
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> While running the chaosmonkey integration tests, it is found that write
> sometimes fails when the cluster components are restarted/stopped/killed etc..
> The data key which was being put, using the LoadTestTool, is added to the
> failed key set, and at the end of the test, this failed key set is checked
> for any entries to assert failures.
> While doing fail-over testing, it is expected that some of the keys may go
> un-written. The point here is to validate that whatever gets into hbase for
> an unstable cluster really goes in, and hence read should be 100% for
> whatever keys went in successfully.
> Currently LoadTestTool has strict checks to validate every key being written
> or not. In case any keys is not written, it fails.
> I wanted to loosen this constraint by allowing users to pass in a set of
> exceptions they expect when doing put/write operations over hbase. If one of
> these expected exception set is thrown while writing key to hbase, the failed
> key would be ignored, and hence wont even be considered again for subsequent
> write as well as read.
> This can be passed to the load test tool as csv list parameter
> -allowed_write_exceptions, or it can be passed through hbase-site.xml by
> writing a value for "test.ignore.exceptions.during.write"
> Here is the usage:
> -allowed_write_exceptions
> "java.io.EOFException,org.apache.hadoop.hbase.NotServingRegionException,org.apache.hadoop.hbase.client.NoServerForRegionException,org.apache.hadoop.hbase.ipc.ServerNotRunningYetException"
> Hence, by doing this the existing integration tests can also make use of this
> change by passing it as property in hbase-site.xml, as well.
