> Reporter: lei w
> Priority: Major
>
> When the last block of the file is in the complete state and the penultimate
> block is in the committed state, LeaseMonitor will continuously check the
> lease of this file. In this case, it is usually because the DN encountered
> some anomalies and did not report to the NN for a long time. So can we renew
> the lease with the LeaseMonitor, and then reduce the number of checks on this
> lease?
