-------------------------------
Summary: BlockManager should output some logs when logEveryBlock
is true.
Key: HDFS-16658
URL: https://issues.apache.org/jira/browse/HDFS-16658
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: ZanderXu
Assignee: ZanderXu
During locating some abnormal cases in our prod environment, I found that
BlockManager does not out put some logs in `addStoredBlock` even though
`logEveryBlock` is true.
I feel that we need to change the log level from DEBUG to INFO.
```
private Block addStoredBlock(final BlockInfo block,
final Block reportedBlock,
DatanodeStorageInfo storageInfo,
DatanodeDescriptor delNodeHint,
boolean logEveryBlock)
throws IOException {
....
if (logEveryBlock) {
blockLog.debug("BLOCK* addStoredBlock: {} is added to {} (size={})",
node, storedBlock, storedBlock.getNumBytes());
}
...
}
```
