-------------------------------------------
Summary: Add robust tools to automatically fix common metadata
problems
Key: ACCUMULO-2413
URL: https://issues.apache.org/jira/browse/ACCUMULO-2413
Project: Accumulo
Issue Type: New Feature
Reporter: Christopher Tubbs
There are some failure cases that can occur, which put the metadata tables in a
corrupted state. Under these circumstances, it'd be useful to have a robust
tool for automatically correcting these mistakes.
Historically, there have been relatively hidden options added to the
CheckForMetadataProblems class, which is an admin utility that is not part of
the public API, for performing some of these tasks. However, these tasks were
not safe to use and never really explained to the user what they did, and were
dropped in ACCUMULO-2291.
A good tool would have a variety of options to cover the different situations
which need to be fixed and would include good documentation, describing the
various repair options, explaining the risks to the user, and prompting them to
confirm, perhaps with the root password.
