Yes, that's it. Waiting for your new release to solve it.

Hi
We use drill to query hbase.
Recently I check one of our query's plan:
0: jdbc:drill:drillbit=rfdc2> explain plan for SELECT '2016-07-27 00:00' as
key, sum(convert_from(action.`v`.`c`,'INT_BE')) AS pv,COUNT(DISTINCT
BYTE_SUBSTR(action.row_key,-8,8)) AS uv,
Hi
I recently use drill to join hbase table. I have one question, does there a
way to make the scan concurrently?
We have a big table and scan very slow. I researched the hbase storage
engine and find there have a similar logic in HBaseGroupScan class which
created a sub scan list for each
nevermind , I changed to jdbc:drill:drillbit=node1;schema=hbase and its
work now.

Sorry , I follow the doc use the url :
jdbc:drill:drillbit=node1/drill/drillbits2;schema=hbase
It's throw java.nio.channels.UnresolvedAddressException. But the host name
is configured in the hosts file.
Did I miss something?
Thanks

We are running query concurrently and get connection through jdbc.
We found that the querys are not distributed equally in the cluster. That
is some nodes have more querys while others are less.
This will cause query running slow at the busy node.
Does there have any way to let the query
I have the same doult.
I set the queue.threshold to 5000, queue.large to 20 and the
queue.small to 200. But when I query with about 100 small querys
concurrently, most of them are ENQUEUED.
If I turn off the queue, it will query fast. If turn on the queue , our
querys will speed about 7
row_key < '0bs' ) t2
on t1.uid = t2.uid limit 10
Now, my work can going on. But I think the first SQL should working too,
hope someone can take a look at it.

But the query is success. Does this exception will affect the query
process, for example will it affect the query speed or data integrity?

Hi Aditya,
I tested the latest version and got this exception and the drillbit fail to
startup .
Exception in thread "main" java.lang.NoSuchMethodError:
io.netty.util.UniqueName.(Ljava/lang/String;)V
at io.netty.channel.ChannelOption.(ChannelOption.java:136)
at
startRow and stopRow can meet it.
for example : select row_key from hbase.browser_action a where
a.row_key >'0' and a.row_key < '1' , I think sql like this will query
faster without rowfilter.

if I put the qualifier "e3" into the table(that is more than 3 qulifier),
then the issue reproduced.

Hi ,
I recently meet a issue that can not query the correct data from hbase with
sql by drill, can anybody help me.
I test with the drill 1.6.
My hbase scheme:
rowkey: salt+day+event+uid + ts , eg: 120160411visituidts
cf : v
qualifier: v, e0, e1
The wrong result only happened when I use group
23 matches
