Can you share more about your setup, specifically what you changed in
your solrconfig file? What version of Solr (looks like a nightly, but
from when)? What did you set auto-commit to be? Can you provide the
full stack trace? Also, were you starting fresh when you got the
second exception?

We are using Solr out of the box, with only a couple of changes in the

We are running a MapReduce job to import into Solr. Every map
creates one
document and used to
add and commit it to Solr. We got
org.apache.solr.common.SolrException:
Error_opening_new_searcher_exceeded_limit_of_maxWarmingSearchers4_try_again_later
,
which we solved by removing the commit statment from the MR job and
added
auto-commit in solrconfig.
We reran the job and got another exception: java.io.IOException:
cannot read
directory org.apache.lucene.store.FSDirectory@/home/solr/src/apache-
solr-nightly/example/solr/data/index:
list() returned null
followed by: SEVERE:
org.apache.lucene.store.LockObtainFailedException: Lock
obtain timed out: SingleInstanceLock: write.lock
This was happening when the number of mappers writing to solr was 6,
we
lowered the number of inputters to 3 and everything worked fine.
Does anyone know what happens, and how we can use more than 3 input
sources
at the same time?
