Tsz Wo Nicholas Sze commented on HDDS-247: ------------------------------------------ For performance reason, ChunkGroupOutputStream/ChunkOutputStream may not be thread safe as the Java OutputStream subclasses are generally non-thread-safe. If users want thread safe, they can easily synchronize it themselves. How about we make both of them non-thread-safe? > Handle CLOSED_CONTAINER_IO exception in ozoneClient > --------------------------------------------------- > > Key: HDDS-247 > URL: https://issues.apache.org/jira/browse/HDDS-247 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Components: Ozone Client > Reporter: Shashikant Banerjee > Assignee: Shashikant Banerjee > Priority: Blocker > Fix For: 0.2.1 > > Attachments: HDDS-247.00.patch, HDDS-247.01.patch, HDDS-247.02.patch, > HDDS-247.03.patch, HDDS-247.04.patch, HDDS-247.05.patch, HDDS-247.06.patch, > HDDS-247.07.patch, HDDS-247.08.patch, HDDS-247.09.patch > > > In case of ongoing writes by Ozone client to a container, the container might > get closed on the Datanodes because of node loss, out of space issues etc. In > such cases, the operation will fail with CLOSED_CONTAINER_IO exception. In > cases as such, ozone client should try to get the committed length of the > block from the Datanodes, and update the OM.
