mon log reporting filenotfound for /logs/hdfs.java.log

[Guy Groulx]

Just noticed on our system that $MY_SQROOT/logs/mon* has many of these

11/12/2014-10:31:15.515.493: (name=monitor/pid=61896/tid=62033) (cmp=1/ev=101130801/fac=320/sev=6): STDERR redirected from n011.$Z001FW1.0.62336: log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: /logs/hdfs.java.log (No such file or directory)

I believe the problem is in the $MY_SQROOT/logs/log4j.hdfs.config file where the following line is:

log4j.appender.hbaseclient.file=${env:MY_SQROOT}/logs/hdfs.java.log

Adding comment from Matt Brown about a fix tried by him in a side branch:

To work around it I made fix to HBaseClient.java to mimic that of DTM HBaseTxnClient.java. Change looks like this

    void setupLog4j() {
        //String confFile = System.getenv("MY_SQROOT")
        // + "/conf/log4j.hdfs.config";
       System.setProperty("trafodion.hdfs.log", System.getenv("MY_SQROOT") + "/logs/trafodion.hdfs.log");
        String confFile = System.getenv("MY_SQROOT")
            + "/conf/log4j.hdfs.config";
        PropertyConfigurator.configure(confFile);
    }

And, similar to DTM’s conf/log4j.dtm.config I changed the conf/log4j.hdfs.config file as follows:

log4j.appender.hbaseclient.file=${trafodion.hdfs.log}

Hello,

Why the "conf" directory. We do not have a "conf" directory under $MY_SQROOT. We have "logs" directory but not a "conf" directory.

Guy, with Manageability will come a conf dir under $MY_SQROOT.

Already a bug open for this

    HBaseClient now logs correctly. Updated copyright

    HbaseClient failed to setup log4j properly due to its
    inability to locate the correct properties file.
