ramkrishna.s.vasudevan commented on HBASE-15709: ------------------------------------------------ So now instead of one packet you chunk it and for every packet you do checksum, data and the header part right? Max data len is 12MB and not 16MB? > Handle large edits for asynchronous WAL > --------------------------------------- > > Key: HBASE-15709 > URL: https://issues.apache.org/jira/browse/HBASE-15709 > Project: HBase > Issue Type: Sub-task > Components: io, wal > Affects Versions: 2.0.0 > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Critical > Fix For: 2.0.0 > > Attachments: HBASE-15709.patch > > > First, FanOutOneBlockAsyncDFSOutput can not work if the buffered data is > larger than PacketReceiver.MAX_PACKET_SIZE(16MB). > Second, since we only allow one block here, we need to make sure we do not > exceed the block size after writing a large chunk of data. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
