AbandonBlockRequestProto cannot be resolved

Hi,

I downloaded the source code from GitHub using the command

git clone git://git.apache.org/hadoop-common.git


and after that installed Eclipse with Maven and EGit and imported that 
into Eclipse by adding the base path into EGit.

While building the project I am getting around 100 errors and one of 
them is mentioned in the subject. I may be doing something fundamentally 
stupid since I am new to JAVA programming.

I will be grateful for any help on this.


Thanks and Regards,
Gourav

Hi,

I reimported the scripts from SVN, followed the instructions in the page 
http://wiki.apache.org/hadoop/EclipseEnvironment and everything seems to 
be working fine now. Though the access restrictions error are still 
showing up as warnings.


Thanks and Regards,
Gourav

Hi Harsh,

when I am building from the command line using the command "mvn clean 
compile" from the root folder then the build is reported as SUCCESSFUL.

Is there any idea then why there are errors shown in the compilation 
when I am importing the project as a Maven Project into Eclipse?

Thanks and Regards,
Gourav

Hi Harsh,

I found the errors in one of the files to that dependencies are not 
found for the following statements:
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.GetServiceStatusRequestProto;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.GetServiceStatusResponseProto;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.HAStateChangeRequestInfoProto;
import org.apache.hadoop.ha.proto.HAServiceProtocolProtos.HARequestSource;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.HAServiceStateProto;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.MonitorHealthRequestProto;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.TransitionToActiveRequestProto;
import 
org.apache.hadoop.ha.proto.HAServiceProtocolProtos.TransitionToStandbyRequestProto;

There is a package called as proto under main which has the classes with 
the name ending as HAServiceProtocolProto (note without the s).

Do I need to clone from GitHub once again?

Regards,
Gourav

Hi Harsh,

I have installed protocol buffers and protoc is in the command path as 
mentioned in the links you had forwarded me before.

I will try the command mentioned and let you know the details.

Gourav

Hi Gourav,

As mentioned on http://wiki.apache.org/hadoop/HowToContribute and
http://wiki.apache.org/hadoop/QwertyManiac/BuildingHadoopTrunk (I
gotta update this for branch-2 (rebranding of branch-0.23 rolling
ahead), etc. now though), did you install the protocol buffers
dependencies on your machine and have the 'protoc' command in PATH?
That may be one cause of these errors you see.

In any case, try a {{mvn clean compile}} from the command line (from
root of the cloned repo) to get more info on what causes a build
failure.
