1 Chunk meta data not loaded and then Write sync failed.
When I move a big file (for example, 4g) to kfs, the error may occur.
And then it will cause lease expired and should be renewed, this will make writing slowly.
2 Retiring write problem
It will occur this problem when write a file to kfs sometimes.
Why a ops does not be prcessed in 5 min after it arrives?
When this situation will occur?
