Jing Zhao created HDFS-8308: ------------------------------- Summary: Erasure Coding: NameNode may get blocked in waitForLoadingFSImage() when loading editlog Key: HDFS-8308 URL: https://issues.apache.org/jira/browse/HDFS-8308 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Jing Zhao Assignee: Jing Zhao
If the editlog contains a transaction for creating an EC file, the NN will get blocked in {{waitForLoadingFSImage}} because the following call path: FSDirectory#addFileForEditLog --> FSDirectory#isInECZone --> FSDirectory#getECSchema --> ECZoneManager#getECSchema --> ECZoneManager#getECZoneInfo --> FSNamesystem#getSchema --> waitForLoadingFSImage This jira plans to fix this bug and also do some code cleanup. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
