Varun Saxena updated HDFS-8474:
-------------------------------
Description:
Impala in CDH 5.2.0 is not compiling with libhdfs.so in 2.7.0 on RedHat 6.4.
This is because getJNIEnv is not visible in the so file.
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
libhdfs.so.0.0.0 returns nothing when following command is run.
"nm -D libhdfs.so.0.0.0 | grep getJNIEnv"
The change in HDFS-7879 breaks the backward compatibility of libhdfs although
it can be argued that Impala shouldn't be using above API.
