hemanthboyina commented on HDFS-14778:
--------------------------------------
+HDFS-9958+ added null check , if the storage is null to return ,
{code:java}
if (storageID != null) {
storage = node.getStorageInfo(storageID);
}
if (storage == null) {
storage = storedBlock.findStorageInfo(node);
}
if (storage == null) {
blockLog.debug("BLOCK* findAndMarkBlockAsCorrupt: {} not found on
{}",blk, dn);
return;
} {code}
they missed out an extra check , we should have a check if the storage
state is failed , we shouldn't create a block if storage state is failed
can refer the scenario from +HDFS-9958+
> BlockManager findAndMarkBlockAsCorrupt adds block to the map if the Storage
> state is failed
