Subject [jira] [Commented] (ACCUMULO-2657) Shard randomwalk fails for 1.6.0
Date Mon, 14 Apr 2014 14:05:15 GMT


Bill Havanki commented on ACCUMULO-2657:

It's not being set explicitly anywhere in the cluster. However, I think I know how it gets

The property is {{@Interpolated}} and has a default value of the empty string (""). When its
default value is retrieved, code in {{Property}} gets it as {{new File("").getAbsolutePath()}},
which comes out to the {{user.dir}} system property.

The property changes because the Concurrent test (and maybe other tests?) stop and restart
servers in a way that {{user.dir}} shifts from one directory to another. That would explain
why Shard by itself kept succeeding for me, because the other tests wouldn't alter the normal
default across the cluster.

A workaround should be to explicitly set that directory to something harmless, maybe /tmp,
so that the default logic doesn't work and the same value is used cluster-wide. I'll give
that a try.
