> Key: HDFS-16332
> URL: https://issues.apache.org/jira/browse/HDFS-16332
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode, dfs, dfsclient
> Affects Versions: 2.8.5, 3.3.1
> Reporter: Shinya Yoshida
> Priority: Major
> Labels: pull-request-available
> Attachments: Screenshot from 2021-11-18 12-11-34.png, Screenshot from

> We're operating the HBase 1.4.x cluster on Hadoop 2.8.5.
> We're recently evaluating Kerberos secured HBase and Hadoop cluster with
> production load and we observed HBase's response slows >= several seconds,
> and about several minutes for worst-case (about once~three times a month).
> The following image is a scatter plot of HBase's response slow, each circle
> is each base's slow response log.
> The X-axis is the date time of the log occurred, the Y-axis is the response
> slow time.
> !Screenshot from 2021-11-18 12-14-29.png!
> We could reproduce this issue by reducing "dfs.block.access.token.lifetime"
> and we could figure out the cause.
> (We used dfs.block.access.token.lifetime=60, i.e. 1 hour)
> When hedged read enabled:
> !Screenshot from 2021-11-18 12-11-34.png!
> When hedged read disabled:
> !Screenshot from 2021-11-18 13-31-35.png!
> As you can see, it's worst if the hedged read is enabled. However, it happens
> whether the hedged read is enabled or not.
> This impacts our 99%tile response time.
> This happens when the block token is expired and the root cause is the wrong
> handling of the InvalidToken exception in sasl handshake in
> SaslDataTransferServer.
> I propose to add a new response code for DataTransferEncryptorStatus to
> request the client to update the block token like DataTransferProtos does.
> The test code and patch is available in
> https://github.com/apache/hadoop/pull/3677
> We could reproduce this issue by the following test code in 2.8.5 branch and
> trunk as I tested
> {code:java}
> // HDFS is configured as secure cluster
> try (FileSystem fs = newFileSystem();
> FSDataInputStream in = fs.open(PATH)) {
> waitBlockTokenExpired(in);
> in.read(0, bytes, 0, bytes.length)
> }
> private void waitBlockTokenExpired(FSDataInputStream in1) throws Exception {
> DFSInputStream innerStream = (DFSInputStream) in1.getWrappedStream();
> for (LocatedBlock block : innerStream.getAllBlocks()) {
> while (!SecurityTestUtil.isBlockTokenExpired(block.getBlockToken())) {
> Thread.sleep(100);
> }
> }
> }
> {code}
> Here is the log we got, we added a custom log before and after the block
> token refresh:
