{code:java}
Couldn't set up IO streams: java.lang.IllegalArgumentException: Failed to
specify server's Kerberos principal name {code}
This error occurs in the org.apache.hadoop.security.SaslRpcClient class. This
problem is caused by the loss of configuration parameters in properties in the
this.conf object. Configuration parameters such as
dfs.namenode.kerberos.principal.pattern cannot be found.

Using the 2.8.5 version of hadoop test, there was no error after the task
failed and restarted, and the data of hive could be loaded into the cache
normally. After the task restarts, the DistributedFileSystem object obtained by
calling the org.apache.hadoop.fs.Path#getFileSystem method is the
DistributedFileSystem object in FileSystem.Cache. The properties object in the
Configuration object of this DistributedFileSystem object contains all
configuration parameters. The properties object in the Configuration object in
the DFSClient#namenode proxy in the DistributedFileSystem object also contains
all the configuration parameters(The Configuration object will be passed to the
org.apache.hadoop.security.SaslRpcClient class eventually use to read the
Configuration parameters), the classloader retained in this Configuration
object is the ChildFirstClassLoader that was set to null before the restart,
but the task will not be affected.

Using the 2.10.1 version of hadoop test, an error was thrown after the task
failed and restarted, and the data of hive could not be loaded into the cache
normally. After the task restarts, the DistributedFileSystem object obtained by
calling the org.apache.hadoop.fs.Path#getFileSystem method is the
DistributedFileSystem object in FileSystem.Cache. The properties object in the
Configuration object of this DistributedFileSystem object contains all
configuration parameters. However, the properties object in the Configuration
object in the DFSClient#namenode proxy in the DistributedFileSystem object also
contains only one configuration parameter(The Configuration object will be
passed to the org.apache.hadoop.security.SaslRpcClient class eventually use to
read the Configuration parameters), the classloader retained in this
Configuration object is the ChildFirstClassLoader that was set to null before
the restart, but the task have been affected. Due to the loss of the properties
configuration parameters, the configuration parameters cannot be obtained when
calling the org.apache.hadoop.security.SaslRpcClient#getServerPrincipal method,
and the error "Failed to specify server's Kerberos principal name" is thrown.

> When I test kafka and hive lookup join, only the connection between tm and
> zookeeper is disconnected after the data is successfully loaded into the

> restart policy is configured (note that the task process does not change at
> this time, and the task restarts in the same container).

> The task did not fail, but hive failed to load data into the cache.
> The hadoop version used in the test is 2.10.1. During the test, it was found
> that changing the hadoop version to 2.8.5 did not throw an exception. Only
> after hive data is loaded to the cache for the first time and the task is
> restarted, the restarted task cannot properly load hive data to the cache;
> The test found that if the nth time (n>=2) load the hive data into the cache
> and the task is restarted, the restarted task can normally load the hive data
> into the cache.
