Andrew Wang updated HDFS-11565: ------------------------------- Attachment: HDFS-11565.002.patch Patch attached. I also reverted the change to the PB tag numbers, which makes it a little less incompatible. > Use compact identifiers for built-in ECPolicies in HdfsFileStatus > ----------------------------------------------------------------- > > Key: HDFS-11565 > URL: https://issues.apache.org/jira/browse/HDFS-11565 > Project: Hadoop HDFS > Issue Type: Improvement > Components: erasure-coding > Affects Versions: 3.0.0-alpha2 > Reporter: Andrew Wang > Assignee: Andrew Wang > Priority: Blocker > Labels: hdfs-ec-3.0-must-do > Attachments: HDFS-11565.001.patch, HDFS-11565.002.patch > > > Discussed briefly on HDFS-7337 with Kai Zheng. Quoting our convo: > {quote} > From looking at the protos, one other question I had is about the overhead of > these protos when using the hardcoded policies. There are a bunch of strings > and ints, which can be kind of heavy since they're added to each > HdfsFileStatus. Should we make the built-in ones identified by purely an ID, > with these fully specified protos used for the pluggable policies? > {quote} > {quote} > Sounds like this could be considered separately because, either built-in > policies or plugged-in polices, the full meta info is maintained either by > the codes or in the fsimage persisted, so identifying them by purely an ID > should works fine. If agree, we could refactor the codes you mentioned above > separately. > {quote} -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
