<!--
Thanks for sending a pull request!
1. If this is your first time, please read our contributor guidelines:
https://cwiki.apache.org/confluence/display/HADOOP/How+To+Contribute
2. Make sure your PR title starts with JIRA issue id, e.g.,
'HADOOP-17799. Your PR title ...'.
-->
### Description of PR
See https://issues.apache.org/jira/browse/HDFS-16332 description for the
detail.
Due to missing handling of invalid token exception in sasl handshake, token
refresh isn't triggered and all datanode is considered as dead nodes.
This causes retry of refetchLocations with sleep and we got bad hbase's
response time.
### How was this patch tested?
- Tested by the intergration test
- Applied this patch to our hadoop and hbase cluster
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?

> 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:

> 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's
> happen 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.
> We could reproduce this issue by the following test code.
> We could reproduce this issue in 2.8.5 branch and trunk with this test code.
> ```
> // HDFS is configured as secure cluster
> try (FileSystem fs = newFileSystem();
> FSDataInputStream in = fs.open(PATH)) {

> Here is the log we got, we added a custom log before and after the block
