Li Bo commented on HDFS-8120: ----------------------------- I think Jing's idea is a good method to solve the problem. I have just uploaded patch 007, changes include:(compare with patch 006) 1.fix bugs in {{TestDFSStripedOutputStream}}; 2. Some unit tests will hang for several seconds when writing. This is not observed using RS(3,2) but obvious using RS(6,3). I have fixed this problem in patch 007(also can create a new jira for this bug). > Erasure coding: created util class to analyze striped block groups > ------------------------------------------------------------------ > > Key: HDFS-8120 > URL: https://issues.apache.org/jira/browse/HDFS-8120 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Zhe Zhang > Assignee: Zhe Zhang > Attachments: HDFS-8120.000.patch, HDFS-8120.001.patch, > HDFS-8120.002.patch, HDFS-8120.003.patch, HDFS-8120.004.patch, > HDFS-8120.005.patch, HDFS-8120.006.patch, HDFS-8120.007.patch > > > The patch adds logic of calculating size of individual blocks in a striped > block group. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
