Ok, let me check that again and come back. is there is any command to get it from Marvel Sense ?
Also please let me know one more information regarding migration.
As mentioned we have ES 0.90.13 in 5 nodes and planning to add additional nodes now (before migration from 0.90.13 to 1.7) so in that case what Java version we need to install in the new nodes, Java 7 or the latest version?
few months ago, i was doing research on upgrading es 0.90.7 to a higher version of es, at that time was 1.5. we had java6 just like your situation running our es cluster 0.90. now if you want ot upgrade to newer es version, you need minimum java7 or better java 8 (underlying lucene requirement) and you need to upgrade java before es. the problem is after java upgrade from 6 to 7, we faced serialization issue in the client reading the data from es cluster.
it was really unfortunate and pity in such condition, upgrade is not achieveable. well, if you have success upgrade, please mesage me. thank you.
