I have a rather large query that took quite a while to execute (11hours, probably on the order of 70B rows), and while the job tracker website we have seems to indicate that the query finished, here is what I see in pig (around the 95% completion mark, and then the reporting simply died):
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/pig/tools/timer/PerformanceTimerFactory at org.apache.pig.Main.run(Main.java:576) at org.apache.pig.Main.main(Main.java:108) Caused by: java.lang.ClassNotFoundException: org.apache.pig.tools.timer.PerformanceTimerFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) ... 2 more While obviously I only care about getting my info (which seems fine and in tact), I thought it was worth mentioning that I saw this in case no one has run across the bug? Especially given that it's important to see bugs that come from actual use and not just local mode testing...
