Description

For tez.runtime.io.sort.mb=3000, following error message is thrown
>>>
info=[Error: Failure while running task:java.lang.RuntimeException: java.io.IOException: Invalid "tez.runtime.io.sort.mb": 3000
>>>

This should mention the range of valid configuration for "tez.runtime.io.sort.mb" (1 to 2047)

For tez.runtime.io.sort.mb=0, following error message is thrown
>>>>
info=[Error: Failure while running task:java.lang.IllegalArgumentException: io.sort.mb should be larger than 0
at com.google.common.base.Preconditions.checkArgument(Preconditions.java:88)
at org.apache.tez.runtime.library.common.sort.impl.ExternalSorter.getInitialMemoryRequirement(ExternalSorter.java:289)
>>>>

This should mention "tez.runtime.io.sort.mb" and not "io.sort.mb".
