Colin Patrick McCabe commented on HDFS-6482: -------------------------------------------- So, when I try to apply your patch locally, I get "git binary diffs are not supported." It looks like different versions of GNU patch have different behavior here (presumably support is a new feature?) and we're playing jenkins roulette. I would say put the tar.gz file in a separate attachment for now, so we can get a jenkins run. > Use block ID-based block layout on datanodes > -------------------------------------------- > > Key: HDFS-6482 > URL: https://issues.apache.org/jira/browse/HDFS-6482 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Affects Versions: 2.5.0 > Reporter: James Thomas > Assignee: James Thomas > Attachments: 6482-design.doc, HDFS-6482.1.patch, HDFS-6482.2.patch, > HDFS-6482.3.patch, HDFS-6482.4.patch, HDFS-6482.5.patch, HDFS-6482.6.patch, > HDFS-6482.7.patch, HDFS-6482.8.patch, HDFS-6482.patch > > > Right now blocks are placed into directories that are split into many > subdirectories when capacity is reached. Instead we can use a block's ID to > determine the path it should go in. This eliminates the need for the LDir > data structure that facilitates the splitting of directories when they reach > capacity as well as fields in ReplicaInfo that keep track of a replica's > location. > An extension of the work in HDFS-3290. -- This message was sent by Atlassian JIRA (v6.2#6252)
