Subject Re: All region server died due to "Parent directory doesn't exist"
Date Wed, 19 Feb 2014 05:47:13 GMT
Hi, all

I think that I may need to further describe the test env. I used for
reproducing this issue.

| hostname | ip | roles |
| aws-scottm-tmh6-1 | 10.147.1.168 | activeNN, ZKFC, JN, ZK, activeJT,
MRZK, NN, TT, HM, RS|
| aws-scottm-tmh6-2 | 10.138.150.16 | standbyNN, ZKFC, JN, standbyJT, MRZK,
NN, TT, HM, RS|
| aws-scottm-tmh6-3 | 10.134.214.132 | JN, NN, TT, RS|

P.S. I currently do not think that this issue is related to MR related
daemons

I would find some other places to put the log files for people interested
in these works.



Best regards

takeshi
