Thomas Mueller updated OAK-1921:
--------------------------------
Description:
I tried to backup a segmentstore (with an external BlobStore) using
{noformat}
java -mx8g -jar oak-run-1.0.2-SNAPSHOT.jar backup segmentstore s2
{noformat}
and got:
{noformat}
Attempt to read external blob with blobId
[c184d2a3f1dbc709004a45ae6c5df7624c2ae653#32768] without specifying BlobStore
at
org.apache.jackrabbit.oak.plugins.segment.SegmentBlob.getReference(SegmentBlob.java:118)
at
org.apache.jackrabbit.oak.plugins.segment.SegmentWriter.writeBlob(SegmentWriter.java:706)
at
org.apache.jackrabbit.oak.plugins.segment.SegmentWriter.writeProperty(SegmentWriter.java:808)
at
org.apache.jackrabbit.oak.plugins.segment.SegmentWriter.writeProperty(SegmentWriter.java:796)
{noformat}
There are two options:
1) Adjust the backup code to work like compaction does, i.e. leave
external blobs as-is and perhaps output a message that informs the
user about the need to use a different mechanism to back up the
BlobStore contents
2) Add command line options for configuring the BlobStore to be used
for accessing external blobs.
