Nemo Chen created HDFS-10752:
--------------------------------
Summary: Variable in byte printed directly in hdfs
Key: HDFS-10752
URL: https://issues.apache.org/jira/browse/HDFS-10752
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.7.2
Reporter: Nemo Chen
Similar to the fix for HBASE-623, in file:
hadoop-rel-release-2.7.2/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/BackupImage.java
In the following method, the log printed variable data (in byte[]). A possible
fix is add Bytes.toString(data).
{code}
/**
* Write the batch of edits to the local copy of the edit logs.
*/
private void logEditsLocally(long firstTxId, int numTxns, byte[] data) {
long expectedTxId = editLog.getLastWrittenTxId() + 1;
Preconditions.checkState(firstTxId == expectedTxId,
"received txid batch starting at %s but expected txn %s",
firstTxId, expectedTxId);
editLog.setNextTxId(firstTxId + numTxns - 1);
editLog.logEdit(data.length, data);
editLog.logSync();
}
{code}
