Hello,
Solr 5.2.1, Zookeeper 3.4.6
I'm trying the use the solr Collection API to migrate documents in a test
environment. I have two collections set up
HotSessions - two shards, no replicas
ColdSessions - 1 shard, no replicas.
I've upload some sample data and using document routing with a split.key of the
date e.g. 05/10/2015!. The command I use to migrate is:
/admin/collections?action=MIGRATE&collection=HotSessions&split.key=05/10/2015!&target.collection=ColdSessions&forward.timeout=60
This returns:
<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">14608</int>
</lst>
<lst name="success">

</response>
In the error logs there is the migrate message
OverseerCollectionProcessor.processMessage : migrate , {
"collection":"HotSessions",
"split.key":"02/10/2015!",
"target.collection":"ColdSessions",
"forward.timeout":"60",
"operation":"migrate"}
Followed by:
-WARN 'no frame of reference to tell if we've missed updates'
-ERROR 'Error removing directory:java.io.IOException: Failed to list contents
of /solr/lost+found
-WARN 'Our node is no longer in line to be leader'
-ERROR 'auto commit error...: java.nio.file.NoSuchFileException:

java.nio.file.NoSuchFileException: /Solr/HotSessions/Index'
-ERROR 'IO error while trying to get the size of the Directory:
java.nio.file.NoSuchFileException: /Solr/HotSessions/ind'
When I query solr- all my session have gone, from both collections. Looking at
the file structure, in my data folder all files have gone apart from a
lost+found folder.
What am I doing wrong? Is there anything in my setup which would cause this or
is my API call wrong?
Any help would be much appreciated.
