Subject [jira] [Updated] (HDFS-2430) The number of failed or low-resource volumes the NN can tolerate should be configurable

Aaron T. Myers updated HDFS-2430:
---------------------------------

    Attachment: HDFS-2430.patch

Here's a patch which fixes the {{TestClusterId}} failure. That test was getting the configured
cluster ID using a backdoor that wasn't bothering to set any edits dirs. The fix was:

{code}

The {{TestAbandonBlock}} and {{TestHDFSCLI}} test failures are unrelated.

> Currently the number of failed or low-resource volumes the NN can tolerate is effectively
hard-coded at 1. It would be nice if this were configurable.
