[jira] Created: (SOLR-1017) Concurrency problem with
last_index_time
Concurrency problem with last_index_time
----------------------------------------
Key: SOLR-1017
URL: https://issues.apache.org/jira/browse/SOLR-1017
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 1.3
Reporter: Ryuuichi Kumai
Attachments: SOLR-1017.patch
The 'last_index_time' value in DIH is not thread-safe.
If data import is executed concurrently (in multiple cores), last_index_time value might be invalid value.
I think this problem is caused by DataImporter#DATE_TIME_FORMAT. The static instance should not be used in many threads since java.text.SimpleDateFormat is not thread-safe.
