Yi Liu created HDFS-8058: ---------------------------- Summary: Erasure coding: use BlockInfo[] for both striped and contiguous blocks in INodeFile Key: HDFS-8058 URL: https://issues.apache.org/jira/browse/HDFS-8058 Project: Hadoop HDFS Issue Type: Sub-task Affects Versions: HDFS-7285 Reporter: Yi Liu Assignee: Yi Liu
This JIRA is to use {{BlockInfo[] blocks}} for both striped and contiguous blocks in INodeFile. Currently {{FileWithStripedBlocksFeature}} keeps separate list for striped blocks, and the methods there duplicate with those in INodeFile, and current code need to judge {{isStriped}} then do different things. Also if file is striped, the {{blocks}} in INodeFile occupy a reference memory space. These are not necessary, and we can use the same {{blocks}} to make code more clear. I keep {{FileWithStripedBlocksFeature}} as empty for follow use: I will file a new JIRA to move {{dataBlockNum}} and {{parityBlockNum}} to INodeFile, since ideally they are the same for all striped blocks in a file, and store them in block will waste NN memory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
