Sean Busbey commented on HBASE-15611:
-------------------------------------
h3. how can I test that replication has caught up and is not blocked for all
region servers handling a given table?
Presuming you know the column families that are set for replication already,
you can hard code them and put a column for each region on the source cluster:
{code}
hbase(main):066:0> example_table = get_table 'MyTable'
hbase(main):067:0> @hbase.admin(@formatter).instance_eval do
@admin.get_table_regions(example_table.table.get_name).each do |region|
hbase(main):068:2* test_row = String.from_java_bytes(region.get_start_key +
"-replication_test".to_java_bytes)
hbase(main):069:2> example_table.put test_row, "f1:replication_test", 'foo'
hbase(main):070:2> example_table.put test_row, "f3:replication_test", 'foo'
hbase(main):071:2> example_table.put test_row, "f4:replication_test", 'foo'
hbase(main):072:2> end end
{code}
Then on each side of replication, a scan should succeed that looks just for
those columns
{code}
hbase(main):086:0> example_table = get_table 'MyTable'
hbase(main):087:0> example_table.scan COLUMNS => ['f1:replication_test',
'f3:replication_test', 'f4:replication_test']
{code}
If any of the row/column combinations don't show up, then you will have the
region name of those stuck replication endpoints.
