> As part of HELIX-452, we decreased the status update cleanup window to 15 minutes and
the error cleanup window to 45 minutes. This makes it more troublesome trying to look back
and find historical errors, and these are proportional to numPartitions * numSessionsInWindow
number of znodes (much less than number of possible status updates). We should increase the
error cleanup threshold to a day.
