Uma Maheswara Rao G updated HDDS-6873:
--------------------------------------
Description:
This Jira is for handling block tokens. At DN ECREconstructionCoordinator we
need to create containers remotely/locally, need to listBlocks on containers,
close containers and read/write chunks. For these operations, we are using
ContainerProtocolsCalls and all of them need tokens.
One idea is, create a lightweight block token manager at DN and generate tokens
and which can be verified at other DN.
For container tokens, we can request from SCM or we can send some tokens from
SCM as part of reconstruction command request. If we send tokens from SCM as
part of command, expiry time should be little longer as the actual
reconstruction work may be started late depending on DN loads and that may not
be safe?.
