zhanglu153 commented on FLINK-30075:
------------------------------------
2.After the properties object in the Configuration object of DFSClient#namenode
proxy in the DistributedFileSystem object is set to null, when is a new
Properties object created?
!call the org.apache.hadoop.conf.Configuration#getProps method to create the
Properties object.png|width=931,height=381!
After the task restarts, call method
org.apache.flink.connectors.hive.read.HiveTableInputFormat#createInputSplits(int,
java.util.List<org.apache.flink.connectors.hive.HiveTablePartition>,
org.apache.hadoop.mapred.JobConf), call method
org.apache.hadoop.fs.FileSystem#exists after getting the filesytem object from
FileSystem.Cache, and finally call method
org.apache.hadoop.conf.Configuration#getProps. Since properties have been set
to null in the reloadConfiguration method, a new Properties object will be
created in the getProps method. However, when calling method
org.apache.hadoop.conf.Configuration#loadResources, you need to call method
org.apache.flink.runtime.execution.librarycache.FlinkUserCodeClassLoaders.SafetyNetWrapperClassLoader#getResources
of Flink to obtain resources. Since the ChildFirstClassLoader used has been
set to null, Flink will throw an exception, which will result in the inability
to reload the configuration properties into the properties object. Therefore,
only a Properties object with size 0 has been created in it.
!hadoop2.10.1
org.apache.hadoop.conf.Configuration#getProps.png|width=546,height=303!
The error thrown when calling the getProps method after properties is set to
null is shown in the following figure:

> 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.
