------------------------------
Summary: RBF: The quota should be set the same as the nearest
parent in Global Quota.
Key: HDFS-14814
URL: https://issues.apache.org/jira/browse/HDFS-14814
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Jinglun
Assignee: Jinglun
I want to add a rule 'The quota should be set the same as the nearest parent'
to Global Quota. Supposing we have the mount table below.
||src||destinations||quota||
|/dir-a|ns0->/dir-a| \{nquota=10,squota=20}|
|/dir-a/dir-b|ns1->/dir-b|{nquota=-1,squota=30}|
|/dir-a/dir-b/dir-c|ns2->/dir-c|{nquota=-1,squota=-1}|
|/dir-d|ns3->/dir-d|{nquota=-1,squota=-1}|
The quota for the remote locations on the namespaces should be:
ns0->/dir-a \{nquota=10,squota=20}
ns1->/dir-b \{nquota=10,squota=30}
ns2->/dir-c \{nquota=10,squota=30}
ns3->/dir-d \{nquota=-1,squota=-1}
The quota of the remote location is set the same as the corresponding
MountTable, and if there is no quota of the MountTable then the quota is set to
the nearest parent MountTable with quota.
It's easy to implement it. In RouterQuotaUpdateService each time we compute the
currentQuotaUsage, we can get the quota info for each MountTable. We can do a
check and fix all the MountTable which's quota doesn't match the rule above.
