 Hi hadoop community,
I trying to install hadoop cluster HA , but datanode does not start properly; I get this errror:
2021-02-23 17:13:26,934 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: Exception in secureMainjava.io.IOException: java.security.GeneralSecurityException: The property 'ssl.server.keystore.location' has not been set in the ssl configuration file.        at org.apache.hadoop.hdfs.server.datanode.web.DatanodeHttpServer.<init>(DatanodeHttpServer.java:199)        at org.apache.hadoop.hdfs.server.datanode.DataNode.startInfoServer(DataNode.java:905)        at org.apache.hadoop.hdfs.server.datanode.DataNode.startDataNode(DataNode.java:1303)        at org.apache.hadoop.hdfs.server.datanode.DataNode.<init>(DataNode.java:481)        at org.apache.hadoop.hdfs.server.datanode.DataNode.makeInstance(DataNode.java:2609)        at org.apache.hadoop.hdfs.server.datanode.DataNode.instantiateDataNode(DataNode.java:2497)        at org.apache.hadoop.hdfs.server.datanode.DataNode.createDataNode(DataNode.java:2544)        at org.apache.hadoop.hdfs.server.datanode.DataNode.secureMain(DataNode.java:2729)        at org.apache.hadoop.hdfs.server.datanode.DataNode.main(DataNode.java:2753)Caused by: java.security.GeneralSecurityException: The property 'ssl.server.keystore.location' has not been set in the ssl configuration file.        at org.apache.hadoop.security.ssl.FileBasedKeyStoresFactory.init(FileBasedKeyStoresFactory.java:152)        at org.apache.hadoop.security.ssl.SSLFactory.init(SSLFactory.java:148)        at org.apache.hadoop.hdfs.server.datanode.web.DatanodeHttpServer.<init>(DatanodeHttpServer.java:197)        ... 8 more
But  in my ssl-server.xml i correctly set this property:
<property>  <name>ssl.server.keystore.location</name>  <value>/data/hadoop/server.jks</value>  <description>Keystore to be used by clients like distcp. Must be  specified.  </description></property>
<property>  <name>ssl.server.keystore.password</name>  <value>xxxx</value>  <description>Optional. Default value is "".  </description></property>
<property>  <name>ssl.server.keystore.keypassword</name>  <value>xxxxx</value>  <description>Optional. Default value is "".  </description></property>
<property>  <name>ssl.server.keystore.type</name>  <value>jks</value>  <description>Optional. The keystore file format, default value is "jks".  </description></property>
Do you have any suggestion to solve this problem?my hadoop version is: 2.8.5java version: 8SO: centos 7

Thanks for your help,
Hamado
