Questions about rpc

[weijie tong]

There's a case that the partitioned sender elapsed lots of time to wait .
>From the profile ,we saw that the sender waits for 1 hour ,the opposite
recivier and its subsequent hash aggregate operator spends 1 hour to its
process time. (39 sender minor fragments,7 reciver minor fragments, each
sender sends about 8m data)Through reading the codes,some opinions and
wonder please correct me.

1. what's design purpose by setting the DataTunnel holds 3 semaphores? to
throttle the sender part ?

2. The profile stats of sender's wait time does not include the reciver's
subsequent operators' process time . right?

3. Is there any advice to accelerate the sender ,receiver phase?

4. The muxechange's purpose is to merge minor fragments belonging to the
same machines to save the sender buffer memory. right?

@parthchandra - Thanks for the feedback. IOException is thrown for various 
reason from FileSystem api's and hence I was just printing the exception

specifically. Now it will print like below.

RE: Understanding the -Dbounds JVM option

[Kunal Khatua]

I believe that flag was renamed

https://github.com/apache/drill/blob/master/exec/memory/base/src/main/java/org/apache/drill/exec/memory/BoundsChecking.java

I might not be the best person to answer this, but it involves enforcing the 
bounds checking of value vectors so that Drill does not access offsets beyond 
the limits (i.e. bounds) of value vectors.
By default, Drill will do bounds checking. Disabling will improve performance, 
but has the potential risk of unsafe memory access which can crash a Drillbit.  

DRILL-5351 had a commit that reduced the number of checks, but couldn't 
eliminate the checks entirely.

This page  refers to a

Would someone please elaborate on the effect of this option or post a link that

RE: compiling drill 1.11.0 with cdh profile

Are you able to access the website mentioned? 
The default profile built successfully, and I'd guess that build should work on 
CDH as well. 

With the CDH profile, I got failure due to dependencies. Need to check why the 
Vectors package failed, but I don't see the problem that you do :

Re: Continuous Integration Tests Failing

I saw that the last commit (9d1d815), which upgrades drill version to
1.12.0-SNAPSHOT, has CI failure, while the two commits before that commit
were shown to have successful CI test. Not clear why update the version
number would cause such difference.

Fallback option manager actually implements setOption and session option 
manager which is a subclass of the fallback option managerdoesn't override 
that. Moreover, we are creating the option value and passing it. So we need to 
have a new method to set option in session option manager. Or can we have a 
variable "type" and set it to OptionType and set it ?

Yes, Correct a System Option Manager is not a fallback for session option 
manager. FragmentOptionManager and SessionOptionManager use SystemOptionManager 
as the fall back manager so for both FragmentOptionManager and 
SessionOptionManager fallback is the System Option Manager so it is returned. 
But in the case of  QueryOptionManager, it uses Session Option Manager as the

Hi Jorg,

can you please first create Drill Jira and describe the problem there and
then link it to your PR?

Kind regards
Arina

Understanding the -Dbounds JVM option

[Muhammad Gelbana]

This page  refers
to a JVM option by the name *bounds*. I tried googling for it but I
couldn't find anything.

Would someone please elaborate on the effect of this option or post a link
that does ?

Thanks,
Gelbana

Spelling mistake in the "system options" page

[Muhammad Gelbana]

I felt it's not a big deal so I thought I don't have a create a Jira task
for it.

On this page

, search for "with have", you should find only one instance, I believe it
should be "will have".


Thanks,
Gelbana
