hi all,

we ran into performance problems by executing several pig-queries. so in our case it is important to see how long needs a pig query. is it possible to see in the logfiles how long needs a pig query to execute? if no is the class "POMapreduce" in method "open()"

sorry i mean at "boolean success = mapReduceLauncher.launchPig(this);"

instead

at "pigServer.store(dbTable.getAlias(), storeFile.toString(), storeStatement);"

e.g.

       long startTime = System.currentTimeMillis();

       boolean success = mapReduceLauncher.launchPig(this);

       long endTime = System.currentTimeMillis();
       long diff = (endTime - startTime) / 1000;
       log.info("launched pig in " + diff + " sec.");


thanks for hints
