While running the nodetool repair , we are running into FileNotFoundException with too many open files error. We increased the ulimit value to 32768, and still we have seen this issue.
THe number of files in the data directory is around 29500+. If we further increase the limit of ulimt, would it help? While tracking the log file for specific file for which it threw the FileNotFoundException, observed that it was part of Compaction. Does it have any thing to do with it? We are using 1.1.4.
