Hi thanks for feedback erik.
What do you mean all the nodes in shards are down? i have 12 shards and i
suppose i have 12 nodes right? correct me if i am wrong.
Now whenever any one of them is down , say 1 down 11 active still i am getting
same error... is there any way to get results ignoring it other than
shard.tolerent=true?
I have replicationFactor=1 ,seems default is 1 so i kept it as it is, if i
change it in my clusterstate.json to 2 or 3 ,is it possible i will get all
results though any node is down?
Regards,
Amey

Hmmm, if all the nodes for a shard are down, shards.tolerant=true
shouldn't be slow unless there's some kind of bug. Solr should be
smart enough not to wait for a timeout. So I'm a bit surprised by that
statement, how sure of it are you? Do you have a test case?
bq: but this is slow and dont gives all results.
Well, you can _never_ have all results if all the replicase for a
shard are down, so the second part of that statement is just the way
the system _has_ to work.
SolrCloud is a wonderful system. The HA/DR handling is predicated upon
at least one member of each shard being available. When you violate
that expectation you have to pay the price of at least incomplete
responses.
Best,
Erick
