Summary: Cross Data Center Replication for existing Indexes
Key: SOLR-9203
URL: https://issues.apache.org/jira/browse/SOLR-9203
Project: Solr
Issue Type: Bug
Components: CDCR
Affects Versions: 6.0
Reporter: Mike Rocke
Hi all,
After several attempts I am unable to get CDCR working for a solr core with
existing documents.
My first attempt failed due to incompatibility with the tlog file names,
Caused by: java.lang.StringIndexOutOfBoundsException: String index out of
range: -1
at java.lang.String.substring(String.java:1967)
at
org.apache.solr.update.CdcrUpdateLog.getLastLogId(CdcrUpdateLog.java:154)
at org.apache.solr.update.UpdateLog.init(UpdateLog.java:282)
at org.apache.solr.update.CdcrUpdateLog.init(CdcrUpdateLog.java:77)
at org.apache.solr.update.UpdateHandler.<init>(UpdateHandler.java:137)
This is going from having an update handler of
<updateLog>
<str name="dir">/somedir/</str>
</updateLog>
to
<updateLog class="solr.CdcrUpdateLog">
<str name="dir">/somedir</str>
</updateLog>
I believe this is due to the file patterns differing for the default update log
class and the CdcrUpdateLog class.
I then continued to follow
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=62687462#CrossDataCenterReplication(CDCR)-FirstTime
which does not describe having the CdcrUpdateLog class, to which solr will now
start erroring with
Caused by: org.apache.solr.common.SolrException: Solr instance is not
configured with the cdcr update log.

I may have completely missunderstood but please advise?
Thanks
