[jira] [Created] (KUDU-2064) Overall log cache usage doesn't respect the limit

Jean-Daniel Cryans created KUDU-2064:
----------------------------------------

             Summary: Overall log cache usage doesn't respect the limit
                 Key: KUDU-2064
                 URL: https://issues.apache.org/jira/browse/KUDU-2064
             Project: Kudu
          Issue Type: Bug
          Components: log
    Affects Versions: 1.4.0
            Reporter: Jean-Daniel Cryans


Looking at a fairly loaded machine (10TB of data in LBM, close to 10k tablets), I can see in the mem-trackers page that the log cache is using 1.83GB, that it peaked at 2.82GB, with a 1GB limit. It's consistent on other similarly loaded tservers. It's unexpected.

Looking at the per-tablet breakdown, they all have between 0 and a handful of MBs.
