In addition to causing thread contention this issue has the potential to cause memory problems. Ran into the following problem. Was using the changes in https://github.com/apache/accumulo-testing/pull/287 to generate bulk imports. This bug in 287 https://github.com/apache/accumulo-testing/pull/288 caused some bulk imports to a single tablet to have lots of files. Did not have the 288 bug fix in testing and ended up with a tablet w/ 25K files. There were lots of concurrent compactions running against this tablet. When these finished they would create a conditional mutation which included the 25k files in a condition. These conditional mutations would cause lots of memory pressure on the tablet server. -- This is an automated message from the Apache Git Service.
