Description

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.

// Some comments here
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());
      }
    ...
  }
