-------------------------------------------
Summary: Indexing threads stuck during network partition can put
leader into down state
Key: SOLR-7109
URL: https://issues.apache.org/jira/browse/SOLR-7109
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.10.3, 5.0
Reporter: Shalin Shekhar Mangar
Fix For: Trunk, 5.1
I found this recently while running some Jepsen tests. I found that some
threads get stuck on zk operations for a long time in
ZkController.updateLeaderInitiatedRecoveryState method and when they wake up
they go ahead with setting the LIR state to down. But in the mean time, new
leader has been elected and sometimes you'd get into a state where the leader
itself is put into recovery causing the shard to reject all writes.
