You need to add generated sources of the project to include generated Proto classes. This blog <http://blog.cloudera.com/blog/2013/05/how-to-configure-eclipse-for-hadoop-contributions/> is old, but will give you some idea on how to import the generated java classes. *The generated sources (e.g. *Proto.java files that are generated using protoc) might not be directly linked and can show up as errors. To fix them, select the project and configure the build path to include the java files under target/generated-sources and target/generated-test-sources. For inclusion pattern, select “**/*.java”.* *- Source : http://blog.cloudera.com/blog/2013/05/how-to-configure-eclipse-for-hadoop-contributions/ <http://blog.cloudera.com/blog/2013/05/how-to-configure-eclipse-for-hadoop-contributions/>* On Fri, Nov 18, 2016 at 8:19 AM, Madhvaraj Shetty <madresearch2...@gmail.com > wrote: > Hi, > > After producing eclipse files from maven, i successfully imported hadoop > project to eclipse.(hadoop-common-project) > > But it has few errors in eclipse: > > AvroRecord cannot be resolved to a type > EchoRequestProto cannot be resolved to a type > TestProtobufRpcProto cannot be resolved > TestProtobufRpcProto cannot be resolved to a type > > I think it is related protocol buffer, but i can't figure out where it is. > > Thanks > > > On Tue, Nov 15, 2016 at 6:27 PM, Mallanagouda Patil < > mallanagouda.c.pa...@gmail.com> wrote: > > > Hi, > > Some time back I have written an article on how to setup development > > environment for Hadoop and also how to debug. > > http://www.codeproject.com/Articles/1067129/Debugging- > > Hadoop-HDFS-using-IntelliJ-IDEA-on-Linux > > > > You can reach me for any issues. > > Thanks > > Mallan > > > > On Nov 15, 2016 5:49 PM, "Brahma Reddy Battula" < > > brahmareddy.batt...@huawei.com> wrote: > > > >> (Keeping user-mailing list in loop.) > >> > >> You can compile corresponding module which you modified. > >> > >> Please refer "Where to run Maven from?" from the following. > >> > >> https://github.com/apache/hadoop/blob/trunk/BUILDING.txt > >> > >> > >> > >> Regards > >> Brahma Reddy Battula > >> > >> -----Original Message----- > >> From: Madhvaraj Shetty [mailto:madresearch2...@gmail.com] > >> Sent: 15 November 2016 19:36 > >> To: general@hadoop.apache.org > >> Subject: Hadoop source code modification. > >> > >> Hello, > >> > >> I am working in the area of hadoop, especially i want to improve hadoop > >> security. > >> > >> So i need procedure for modifying hadoop source code. > >> I have visited this <https://wiki.apache.org/hadoop/HowToContribute>and > >> able to compile hadoop from the source code, but i need to modify the > >> part of the code. > >> > >> Is it compulsory to compile the whole hadoop, can i compile/debug a part > >> of it.
