------------------------------------------
Hi [~linyiqun], HDFS-13346 handles the synchronization part but if you see the
RouterAdmin
{code:java}
private boolean clrQuota(String mount) throws IOException {
return updateQuota(mount, HdfsConstants.QUOTA_DONT_SET,
HdfsConstants.QUOTA_DONT_SET);
}
{code}
clrQuota() is sending HdfsConstants.QUOTA_DONT_SET to clear the quota, because
of this quota is not getting cleared in nameservice side.
In FSDirAttrOp#unprotectedSetQuota
{code:java}
if (nsQuota == HdfsConstants.QUOTA_DONT_SET) {
nsQuota = oldNsQuota;
}
if (ssQuota == HdfsConstants.QUOTA_DONT_SET) {
ssQuota = oldSsQuota;
}{code}
So, Instead of HdfsConstants.QUOTA_DONT_SET we need to send
HdfsConstants.QUOTA_RESET to clear the quota.
