[jira] [Updated] (HDFS-17052) Erasure coding reconstruction failed when num of storageType rack NOT enough
[ https://issues.apache.org/jira/browse/HDFS-17052?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hualong Zhang updated HDFS-17052:
---------------------------------
Description:
When writing EC data, if the number of racks with DN that match the storageType of the file is insufficient, multiple data blocks are allowed to be written to the same rack.
However, during EC block recovery, it is not possible to recover on the same rack, which deviates from the expected behavior."
