Heng Chen commented on HBASE-14815:
-----------------------------------

The reason is that  we set  mapreduce.map.maxattempts to 10 in 
TestMobExportSnapshot.

It is reasonable for other tests but not suitable for testExportFailure. 
Because each mapper will failed in testExportFailure,  MRCluster will retry too 
many times.
IMO we should decrease this number for testExportFailure.
