RE: [Discuss] Remove server from RSGroup

[Pankaj kr]

Why do we need to track such dead servers which are not going to come back. 
Pardon, maybe I missed some pointer.

Any thought?

Moving any dead region servers to default rsgroup would remove them from knows

RE: [DISCUSS] Move stable pointer to the latest 2.3.x release

[Pankaj kr]

We have observed performance degrade in Scan and Bulk load as compared to 1.x, 
there are couple of JIRAs already in-progress to handle them HBASE-24754, 
HBASE-24637 & HBASE-24850.
IMO we should move stable pointer after fixing these important issues.

Hello everyone,

While voting for 2.2.6 RC0, we had a short discussion reg moving stable pointer 
to the latest 2.3.x and the decision was to initiate the discuss thread when 
2.3.1 and 2.2.6 are out.

Since 2.3.1 is already out and our RM is busy with 2.2.6 release process, I am 
initiating this thread to discuss the same.

Would you all like to consider moving stable release pointer to 2.3.x release 
line?
Given the stabilization efforts and some latest features available with stable 
tests, I am +1 for the same.

Could not reseek StoreFileScanner[HFileScanner

This exception occurred multiple times in the same environment and same problem 
observed even though region was reassigned to different RS. To ensure the HFile 
is not corrupted we copied the HFile into another cluster but read was 
successful.
Problem got resolved after major compaction in the production environment.

Production environment is using HBase 1.3.1 + OS JIRA bug fixes.

Anyone met this problem in their environment, any lead would be greatly 
appreciated.

RE: [DISCUSS] Moving towards a branch-2 line that can get the 'stable' pointer.

[Pankaj kr]

Yeah, HBCK2/ OfflineMetaRepair tools are really required to migrate old version 
data to HBase-2. We have use cases where we are using these tools to rebuild 
the meta for further region assignment.
Similar discussion is going on HBASE-21665, after fixing the NPE and rebuilding 
the meta, master don't assign the regions as we skip the empty regions while 
loading meta during master startup.

A big +1 from my side on this...

RE: Rough notes from dev meetup, day after hbaseconasia 2018, saturday morning

Agree with Andrew, adding SQL capability to HBase will be little messy task and 
not much value added to HBase when solutions like phoenix already available. 

>>> If SQL support is really the goal it would be better to assist there. Or, 
>>> if the goal is the barest minimal SQL-like thing someone needs to support 
>>> their use case, and then contribute to HBase, call it something else, like

It would be helpful if someone could forward the relevant bits of Phoenix 
discussion to the Phoenix dev list. One thing I know that project lacks is 
usability feedback. I don't see anyone writing in with suggestions, mainly 
complaining about it on a HBase list somewhere. Could just be I lack 
perspective and those conversations are happening somewhere, but I am a 
subscriber to all of the relevant lists and this is my observation. If a 
correct observation, this is not really fair. I work somewhere that has Phoenix 
in production. There is no doubt the attempt to implement RDBMS functionality 
*inside* HBase as an add on component is a challenging undertaking. However, 
any would be substitute I have seen to date either doesn't actually attempt the 
same challenges, or takes a shortcut which renders any comparison to the 
proverbial "apples and oranges". The tell here is the notion of *lightweight* 
SQL access. Reads as a tremendous limitation of scope. SQL is a huge standard 
incorporating 30+ years of development in relational systems capabilities and 
semantics. We will get into trouble if we ever attempt a "lightweight" SQL 
interface to HBase that fails to match expectations which automatically attach 
to the effort whenever you claim it to be a SQL interface. This is a cross the 
Phoenix project already bears. If SQL support is really the goal it would be 
better to assist there. Or, if the goal is the barest minimal SQL-like thing 
someone needs to support their use case, and then contribute to HBase, call it 
something else, like Cassandra did with CQL. Would be like the other connectors 
- thrift, REST, Kafka, etc. - and should go into the connectors repo, in my 
opinion.

RE: Region comapction failed

[Pankaj kr]

Yeah, HBASE-13123 already available.

While going through HFilePrettyPrinter result with -e option, we observed some 
keys doesn't contain complete column_family:qualifier information. Normally in 
HFIle Keys are formed as,
K: r1/CF:Qualifier/1484302946516/Put/vlen=1/seqid=0

But some records,
K: r1/Unknown_Qualifier/1484302946516/Put/vlen=1/seqid=0
Here there is no column family detail, normally it is like column family name 
and the colon (:) .

It's strange, how key is written in wrong format in HFile.

RE: Region comapction failed

[Pankaj kr]

Thanks Ted for replying.

Actually issue happened in production environment and there are many HFiles in 
that store (can't get the file). As we don't log the file name which is 
corrupted, Is there anyway to get the corrupted  file name? 

Block encoding is "NONE", table schema has bloom filter as "ROW", compression 
type is "Snappy" and durability is SKIP_WAL.


Regards,
Pankaj

In the second case, the error happened when writing hfile. Can you track down 
the path of the new file so that further investigation can be done ?

Does the table use any encoding ?

Thanks

HBase version : 1.0.2

We have verified all the HFiles in the store using HFilePrettyPrinter with "k" 
(checkrow), all report is normal. Full scan is also successful.
We don't have the access to the actual data and may be customer wont agree to  
share that .

Have anyone faced this issue, any pointers will be much appreciated.

Listen port will be bind always to the passed command line address

[Pankaj kr]

Hi,

In Thrift server,  listen port will be bind always to the 
address which  is passed through command line argument.
--
InetSocketAddress inetSocketAddress = bindToPort(cmd.getOptionValue(bind), 
listenPort);
-

private static InetSocketAddress bindToPort(String bindValue, int listenPort)
  throws UnknownHostException {
try {
  if (bindValue == null) {
return new InetSocketAddress(listenPort);
  } else {
return new InetSocketAddress(InetAddress.getByName(bindValue), 
listenPort);
  }
} catch (UnknownHostException e) {
  throw new RuntimeException(Could not bind to provided ip address, e);
}
  }

In case when bind address is not passed through argument then 
it is binding with any local  address. It should read 
hbase.thrift.info.bindAddress  value from configuration first.

Shall I raise a Jira and  implement this change?

Regards,
Pankaj
