> I thought of a way to fix HBASE-3515 that has a very broad impact, so I'm creating this jira to *raise awareness* and gather comments.
> Currently when we call HRS.abort, it's still possible to do HDFS operations like rolling logs and flushing files. It also has the impact that some threads cannot write to ZK (like the situation described in HBASE-3515) but then can still write to HDFS. Since that call is so central, I think we should {color:red} add fs.close() inside the abort method{color}.
> The impact of this is that everything else that happens after the close call, like closing files or appending, will fail in the most horrible ways. On the bright side, this means less disruptive changes on HDFS.
> Todd pointed at HBASE-2231 as related, but I think my solution is still too sloppy as we could still finish a compaction and immediately close the filesystem after that (damage's done).
