https://issues.apache.org/jira/browse/HBASE-24994 Hedged reads use same thread pool for the original read: https://github.com/apache/hadoop/blob/0b8464d75227fcee2c6e7f2410377b3d53d3d5f8/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSInputStream.java#L1349-L1357 When the executor is full and rejects the task, it will be executed in current thread, increasing this metric: https://github.com/apache/hadoop/blob/0b8464d75227fcee2c6e7f2410377b3d53d3d5f8/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSClient.java#L2913-L2918 I want to expose this metric to HBase since it will be useful to estimate the correct thread pool size. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
