> No idea why {{hbase_handler_bulk.q}} does not catch this if its being run regularly in
Hive builds, but here's the gist of the issue:
> The condition at
indicates that we will infinitely loop until we find a file whose last path component (the
name) is equal to the column family name.
> In execution, however, the iteration enters an actual infinite loop cause the file we
end up considering as the srcDir name, is actually the region file, whose name will never
match the family name.
> This is an example of the IPC the listing loop of a 100% progress task gets stuck in:

> The path we are getting out of the listing results is {{/user/hive/warehouse/hbase_test/_temporary/1/_temporary/attempt_1436935612068_0011_m_000000_0/family/97112ac1c09548ae87bd85af072d2e8c}},
but instead of checking the path's parent {{family}} we're instead looping infinitely over
its hashed filename {{97112ac1c09548ae87bd85af072d2e8c}} cause it does not match {{family}}.
> It stays in the infinite loop therefore, until the MR framework kills it away due to
an idle task timeout (and then since the subsequent task attempts fail outright, the job fails).
> While doing a {{getPath().getParent()}} will resolve that, is that infinite loop even
necessary? Especially given the fact that we throw exceptions if there are no entries or there
is more than one entry.
