CDH 5.4.4. - unable to start Oozie

I keep running into this while attempting to install CDH 5.4.4. I checked the 'create database' and seems to have worked fine. Please let me know what else might be causing this error:

Re: CDH 5.4.4. - unable to start Oozie

If I do the override of the "oozie.services" property using a subset of the services list, I'm able to start the Oozie server:

 

<property>
    <name>oozie.services</name>
    <value>org.apache.oozie.service.SchedulerService,org.apache.oozie.service.InstrumentationService,org.apache.oozie.service.MemoryLocksService,org.apache.oozie.service.UUIDService,org.apache.oozie.service.ELService,org.apache.oozie.service.AuthorizationService,org.apache.oozie.service.UserGroupInformationService,org.apache.oozie.service.HadoopAccessorService,org.apache.oozie.service.JobsConcurrencyService,org.apache.oozie.service.URIHandlerService,org.apache.oozie.service.DagXLogInfoService,org.apache.oozie.service.SchemaService,org.apache.oozie.service.LiteWorkflowAppService</value>
  </property>

 

Upon adding a few more services to the end of the list comes back with the same error:

 

 E0103: Could not load service classes, Unmatched braces in the pattern.

 

I'm not sure if this is some sort of misconfiguration on my part?

Re: CDH 5.4.4. - unable to start Oozie

The problem is very silly, the password has character "{".

 

Caused by: java.lang.IllegalArgumentException: Unmatched braces in the pattern.

The code is:

 

String connProps = "DriverClassName={0},Url={1},Username={2},Password={3},MaxActive={4}";
connProps = MessageFormat.format(connProps, driver, url, user, password, maxConn);

 

Replace "{3}" by the password with character "{", and the last MessageFormat.format can find end character "}"


final Properties props = new Properties();
if (autoSchemaCreation) {
  connProps += ",TestOnBorrow=false,TestOnReturn=false,TestWhileIdle=false";
  props.setProperty("openjpa.jdbc.SynchronizeMappings", "buildSchema(ForeignKeys=true)");
}
else if (validateDbConn) {
  // validation can be done only if the schema already exist, else a
  // connection cannot be obtained to create the schema.
  final String interval = "timeBetweenEvictionRunsMillis=" + evictionInterval;
  final String num = "numTestsPerEvictionRun=" + evictionNum;
  connProps += ",TestOnBorrow=true,TestOnReturn=true,TestWhileIdle=true," + interval + "," + num;
  connProps += ",ValidationQuery=select count(*) from VALIDATE_CONN";
  connProps = MessageFormat.format(connProps, dbSchema);
}
