Change subject: IMPALA-4278: Don't abort Catalog startup quickly if HMS is not present

Patch Set 2:

> range?

You could validate that it was > 0, but otherwise I don't think you should put a bound
on it. Users may want to wait effectively forever, and I can see them setting 9999999999 as
a value to simulate that.

> Adding this config parameter to the CM UI is another issue. Do you think it should  be
added for the 5.10 release or it is not that urgent? I guess, the default value is reasonable
for most users and they can always set it as a safety valve if they have to.

Sounds like you're talking about a Cloudera release. Reminder that this is the Apache Impala
project - vendor specific concerns should be discussed elsewhere.
