I am relatively recent addition to the HBase community. Since I started working on the HBase, I had a few opportunities to debug the HBase code. I would like to share with you the Logging Guidelines Document with the goal to improve the readability and debuggability of HBase log files. I would appreciate your reviews, suggestions, thoughts on this. Similar set of guidelines helped us in the past. I hope HBase will benefit from it as well. You can view the document here: *https://docs.google.com/document/d/1a7P2MiUGpHKK0-BFk3zGQ-2g5Kwvw7P-3zTtd-Vdvg8 * . Thanks, Umesh --001a113744a6a655ba05419a24bf--
