[jira] [Resolved] (KUDU-2753) kudu cluster rebalance crashes with core dump

2019-03-29 Thread Will Berkeley (JIRA)

Will Berkeley resolved KUDU-2753.
-
   Resolution: Won't Fix
Fix Version/s: n/a

This is a problem with the downstream Kudu vendor's code, specifically, with 
how it is using the std::regex library to do some version detection, which 
causes crashes on some platforms because the regex library was broken. You 
should approach Cloudera about a fix or workaround.

It looks like this feature already exists, but configuring the maximum number 
is "experimental". This jira can just track changing `max_log_files` to stable.
