> 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.
