Todd Lipcon commented on IMPALA-2029: ------------------------------------- This has come up again with new Hadoop releases. Going to take another approach here: rather than trying to create the VM ourselves, we'll just call into a libhdfs function, let libhdfs do the attaching, and then use the GetEnv() JNI call to find the attached environment. That simplifies the worries about agreeing on who will do the _detach_. > Impala in CDH 5.2.0 fails to compile with hadoop 2.7 > ---------------------------------------------------- > > Key: IMPALA-2029 > URL: https://issues.apache.org/jira/browse/IMPALA-2029 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 2.2 > Environment: Red Hat 6.4 and gcc 4.3.4 > Reporter: Varun Saxena > Assignee: Todd Lipcon > Priority: Major > > Compilation fails with below error message : > ../../build/release/exec/libExec.a(hbase-table-scanner.cc.o): In function > `impala::HBaseTableScanner::Init()': > /usr1/code/Impala/code/current/impala/be/src/exec/hbase-table-scanner.cc:113: > undefined reference to `getJNIEnv' > ../../build/release/exprs/libExprs.a(hive-udf-call.cc.o):/usr1/code/Impala/code/current/impala/be/src/exprs/hive-udf-call.cc:227: > more undefined references to `getJNIEnv' follow > collect2: ld returned 1 exit status > make[3]: *** [be/build/release/service/impalad] Error 1 > make[2]: *** [be/src/service/CMakeFiles/impalad.dir/all] Error 2 > make[1]: *** [be/src/service/CMakeFiles/impalad.dir/rule] Error 2 > make: *** [impalad] Error 2 > Compiler Impala Failed, exit > This issue is coming because libhdfs in hadoop 2.7.0 has made visibility of > getJNIEnv() as hidden. > But shouldn't Impala create its own JNIEnv ? > These HBase related files seem to have no direct connection with libhdfs -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
