Since "Import Kerberos Account Manager Credentials" tab show blank for both User name and Password, I have no clue which user is used. Basically I will create a new account manager then.

I am trying to bootstrap a CDH 5.9.1 cluster with MIT KDC in AWS. The same configuration works without kerberos. The application log didn't show any error. The bootrap command failed as follows: ... * Enabling Kerberos ............................................................................................................................................................ done * Calling firstRun on cluster m7test ... done * Waiting for firstRun on cluster m7test .............................................................................................................................................................. done * Collecting diagnostic data ................................................................................................................ done * Cloudera Manager 'First Run' command execution failed: Failed to perform First Run of services. ... I logged into CM and saw HDFS data nodes all failed to start. DN failed to authenticate with NN.

Thanks. As a workaround, I just disable password validation via ansible script right after mysql initial installation.

MySQL 5.7 is listed as supported DB version. However, Cloudera Director generates passwords not suitable for 5.7 standard. Application log is shown as follows: [2017-01-24 22:46:13] INFO [io-thread-38] - ssh:10.3.1.154: [ main] DbProvisioner ERROR Stack Trace: [2017-01-24 22:46:13] INFO [io-thread-38] - ssh:10.3.1.154: java.sql.SQLException: Your password does not satisfy the current policy requirements [2017-01-24 22:46:13] INFO [io-thread-38] - ssh:10.3.1.154: at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1078)[mysql-connec tor-java.jar:]

Same thing happened to me. Used curl on edge node without any issue.

I am not using iptables, using firewalld instead on Centos 7.x. The error I saw is caused by Hive doing select count(*) on a table, and the log indicates that the communication is between two slave nodes, not between edge node and AM. Please check your test setting. If your range is large enough, some jobs might succeed. With my current setting of 6000 port range, some jobs failed, and some succeeded by retrying and hitting the port within the range.

Redeployed the client configuration from CM. Checked both yarn and hive configuration, both mapred-site.xml files have the correct configuration reflected.
