Subject [GitHub] adamjshook opened a new issue #535: WAL recovery enhancements and tooling
Date Wed, 20 Jun 2018 17:34:25 GMT
adamjshook opened a new issue #535: WAL recovery enhancements and tooling
URL: https://github.com/apache/accumulo/issues/535
 
 
   The changes in #458 introduced a number of state checks that we are experiencing.  As far
as I know there isn't any tooling around troubleshooting corrupt WAL files that are unrecoverable
by Accumulo (please correct me if I am wrong!) and replacing the WAL with an empty one isn't
a good option.
   
   I'd like to know a little more about the various `IllegalStateExceptions` themselves and
what kind of WAL surgery could be done.  Either creating a new tool to manually assist with
recovery of the mutations or enhancements to the process itself so Accumulo can make the choices
for us.
