Key: HDFS-8617 URL: https://issues.apache.org/jira/browse/HDFS-8617 Project: Hadoop HDFS Issue Type: Improvement Components: HDFS Affects Versions: 2.7.0 Reporter: Lei (Eddy) Xu Assignee: Lei (Eddy) Xu
As described in HDFS-8564, {{DiskChecker.checkDirs(finalizedDir)}} is causing excessive I/Os because {{finalizedDirs}} might have up to 64K sub-directories (HDFS-6482). This patch proposes to limit the rate of IO operations in {{DiskChecker.checkDirs()}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
