Recently we want to delete some c* nodes for data migration. C* verision:2.0.15 we use nodetooldecommission with nohup: nohup nodetool decommission -h xxx After execute 3 days already, seems this process did’t finished yet! This decommissioning Node data isnearly 400G.
1. I check jps -lm, and NodeCmd decommission process still there. 2. and nohup.out file is empty always. 3. I check opscenter, the node status is Leaving: 1 running task. 4. the running task is Compaction, I use nodetool stop compaction, but after sometime later compaction happend again. 5. thenodetool netstats show it’s leaving: Mode: LEAVING Unbootstrap 928e6be0-7950-11e5-9cfb-910d8a1425c3 ….

Or does something wrong inside? just 400G data takes 3 days(and still unfinished) seems abnormal. Tks, qihuang.zheng
