SammiChen created HDFS-12394: -------------------------------- Summary: Erasure coding policy cell size should not be greater than file block size Key: HDFS-12394 URL: https://issues.apache.org/jira/browse/HDFS-12394 Project: Hadoop HDFS Issue Type: Improvement Components: erasure-coding Affects Versions: 3.0.0-alpha4 Reporter: SammiChen
Current the minimum block size is defined by "dfs.namenode.fs-limits.min-block-size" with default value 1MB. Default block size is defined by "dfs.blocksize" with default value 128MB. Maximum erasure coding policy cell size is defined by "dfs.namenode.ec.policies.max.cellsize" with default value 4MB. We need to make sure the erasure coding policy cell size should not. be greater than file block size, file read/write will fail. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
