Howdy all. So I now have HICC displaying Hadoop metrics (yay!)
But it seems to work wonkily. I was messing around with adding new things to display, and wound up injuring hicc somehow. Symptom: a whole bunch of graphs refuse to display, just drawing whitespace. And intead of showing actual machine names, the host selector widget has HTTP escapes around the names. So "hostname" got replaced with %22hostname%22. Why? I had the following in my catalina.out: May 21, 2009 5:31:46 PM org.apache.catalina.startup.Catalina start ----------- INFO: Server startup in 23689 ms 09/05/21 20:28:57 ERROR hicc.DatasetMapper: SQLException: Unknown column 'heartbeat_avg_time' in 'field list' 09/05/21 20:28:57 ERROR hicc.DatasetMapper: SQLState: 42S22 09/05/21 20:28:57 ERROR hicc.DatasetMapper: VendorError: 1054 09/05/21 20:28:57 ERROR hicc.DatasetMapper: SQLException: Unknown column 'heartbeat_avg_time' in 'field list' 09/05/21 20:28:57 ERROR hicc.DatasetMapper: SQLState: 42S22 09/05/21 20:28:57 ERROR hicc.DatasetMapper: VendorError: 1054 09/05/21 20:33:08 ERROR hicc.DatasetMapper: SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%27 %27,process_name) as process,threads_blocked from hadoop_jvm_479_month where' at line 1 09/05/21 20:33:08 ERROR hicc.DatasetMapper: SQLState: 42000 09/05/21 20:34:02 ERROR hicc.DatasetMapper: VendorError: 1064 09/05/21 20:39:13 INFO util.XssFilter: XssFilter.getParameterValues: cannot get parameter for: table 09/05/21 20:39:13 ERROR hicc.DatasetMapper: SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from cluster_system_metrics_2055_week where timestamp >= '2009-05-22 02:39' and ' at line 1 09/05/21 20:39:13 ERROR hicc.DatasetMapper: SQLState: 42000 09/05/21 20:39:13 ERROR hicc.DatasetMapper: VendorError: 1064 09/05/21 20:43:16 ERROR hicc.DatasetMapper: SQLException: Unknown column 'hosts' in 'field list' 09/05/21 20:43:16 ERROR hicc.DatasetMapper: SQLState: 42S22 -------- -- Ari Rabkin [email protected] UC Berkeley Computer Science Department
