Hello,
we are using Solr 7.7.2 and sometimes we are performing a full reindex
of a core. Therefor we stop the replication on the master
(solr/<core>/replication?command=disablereplication),
we backup and delete the index, finally we rebuild the index and enable
the replication again.
However, the moment we stop the replication on the master, the
Slave-Solr's delete their index.
This behavior is also described in the issue
https://issues.apache.org/jira/browse/SOLR-11938, but without any
comments yet.
This seems to be a result of fixing the issue
https://issues.apache.org/jira/browse/SOLR-11293
Because if I rollback the line in IndexFetcher.java
from "if (commit.getGeneration() != 0)"
to "if (forceReplication && commit.getGeneration() != 0)"
back, then everything works fine, it means that the slaves stop deleting
her indexes after turning off the replication.
Is this behavior with stopping replication and loosing the index a known
problem?
Has anyone else had the problem and knows how to solve it?
I am not sure, what will be fail, if i revert the line in
IndexFetcher.java.
Thanks and regards
Mahmut
