Hi, We have a 6 machine hive cluster. We are getting errors while a query is running and it fails. I found that on all 5 slaves storage is nearly full ( 96%, 98%, 100%, 97%, 98% storage used) .
On my slaves machines, this folder "/mnt/hadoop-fs/dfs/data/current/" is contributing 95% storage used. It contains folders with names "subdir0", "subdir1", etc and under them there are many files with name like "blk_-4071357924681234567" and blk_-4071357924681234567_246813.meta:, etc. I want to delete these subdir folders but I am not sure if it will not affects the tables which I have created. Can anyone help me and tell me what are these folders used for ?. Thanks, Chunky.
