Hi
I deployed a solr cluster,the code version is
"NightlyBuilds apache-solr-4.0-2012-03-19_09-25-37".
Cluster has 4 nodes named "A", "B", "C", "D", "num_shards=2", A and
C in shard1 , B and D in shard2, A and B is the leader of their shard. It
has ran 2 days, added 20m docs, all of then are OK, but after this ,C
occured a Exception "org.apache.lucene.store.AlreadyClosedException: this
IndexWriter is closed", and jetty on C was not down, node C exist in
zookeeper in "/live_nodes". In this time, The A try to ask C to recover,
but C can't an response, so A get a Exception, the log is:
<D0><C5>Ϣ: try and ask http://node23:8983/solr to recover

There are 2400 lines log as above at 8:02:36 in 1 second, and it is not
over until I shut down the C's jetty server. The important is the client
can 't add any document to cluster in this time, it will recover after C
server shutdown also.
/clusterstate.json data in zookeeper is:
{"mblog":{
"shard1":{
"A:8983_solr_mblog":{
"shard":"shard1",
"leader":"true",
"state":"active",
"core":"mblog",
"collection":"mblog",
"node_name":"A:8983_solr",
"base_url":"http://A:8983/solr"},
"C:8983_solr_mblog":{
"shard":"shard1",
"state":"recovering",
"core":"mblog",
"collection":"mblog",
"node_name":"C:8983_solr",
"base_url":"http://C:8983/solr"}},
"shard2":{
"B:8983_solr_mblog":{
"shard":"shard2",
"state":"active",
"leader":"true",
"core":"mblog",
"collection":"mblog",
"node_name":"B:8983_solr",
"base_url":"http://B:8983/solr"},
"D:8983_solr_mblog":{
"shard":"shard2",
"state":"active",
"core":"mblog",
"collection":"mblog",
"node_name":"D:8983_solr",
"base_url":"http://D:8983/solr"}}}}
The last question is how to config the solr_cluster.properties file and
excute the Cluster Admin Commands described in
http://wiki.apache.org/solr/NewSolrCloudDesign ?
