Hi all I'm learning HBase and I faced a following problem. I'm running HBase 0.20.3 on Windows+Cygwin (just bin/start-hbase.sh). I'm creating simple table in a shell: hbase(main):033:0> create 't1', 'f1' 0 row(s) in 2.0630 seconds Then I'm trying to execute following JUnit test - and it fails on last assert. Literally - it inserts a value, deletes a row and inserts value to same id again. When it tries to Get data for given row, null is returned. When I try to rerun test again, it fails on first assert. To fix it I have to run 'truncate 't1'' in my shell. I can't believe there's a bug in such straightforward use case, so either I do something wrong in a code or there's a problem with my configuration. Thanks. JUnit test: @Test public void sequentUses() throws IOException { HTable table = pool.getTable("t1"); try { Put put = new Put("row-id".getBytes()); put.add("f1".getBytes(), "c1".getBytes(), 1L, "v1".getBytes()); table.put(put); Get get = new Get("row-id".getBytes()); get.setMaxVersions(Integer.MAX_VALUE); Result res = table.get(get); assertNotNull(res.list()); table.delete(new Delete("row-id".getBytes())); put = new Put("row-id".getBytes()); put.add("f1".getBytes(), "c1".getBytes(), 1L, "v2".getBytes()); table.put(put); res = table.get(get); assertNotNull(res.list()); } finally { pool.putTable(table); } }
