That's good enough for me. Eventually it will be fixed then I presume.


I'll add a note to the wiki.

My bad !! That was a configuration issue - HBASE-2134 should be in thatfixes the issue.

Blowing away the Ivy cache resolved this.

apurt...@latitude:~/src/Hadoop/hbase-trunk$ ant&&   ant test

And all is well.

Hitting this for the first time at 3am is annoying.

Any chance there is some update to the Ivy config which can handle this
automagically?

Sorry about that.. Been looking at IVY-938 - that seems to be an issue
with Ivy in recognizing this . Can you log an improvement if this needs
to be tracked .

An optimization for the ivy cache deletion though.  You can do  $ rm -rf
~/.ivy2/cache/org.apache.hadoop/* as opposed to everything else in the
cache.
