Joseph commented on HBASE-8700:
-------------------------------
Hello I was just playing around with the IntegrationTestBigLinkedList and was
wondering how you use command line to specify optional values outside of the
IntegrationTestBase optionals?
For example how do I specify the logging frequency of a Walker in command line?
Because when I run the following:
./hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList walker -l 1000
I receive:
Unrecognized option: org.apache.commons.cli.UnrecognizedOptionException:
Unrecognized option: -l from the parser in processOptions()
Do I just have to register all possible optionals in an overridden addOptions
method like in IntegrationTestReplication.addOptions()?
Sorry I am pretty new to this and thanks!

> The test can fail due to random number collision, claiming there are
> unreferenced elements for obvious reasons (we rewrite some link). Original
> Accumulo test has one-stage generation so it doesn't count unreferenced
> elements as failures, only undefined ones. With 200m longs out of half-long
> range the probability of collision is approx 0.2%.
> Moreover, without some way to debug, it's hard to debug what keys should be
> looked at in such cases
