Matteo Bertozzi commented on HBASE-5666:
----------------------------------------
@Ted woo good catch
I've just "translated" the method without thinking...
and this "simplified" version emphasizes a problem already present in the
previous version.
If you take a look at the original version, (the LOG.info is under if, ok)
but what happens if the method return and the znode is not available?
no exception is raised... but I think that the caller of waitForXyz() expect
some exception in case of timeout, in the other case the value that I'm looking
for must be present...
(this function is just called by one test)
