hadoop - Hive Could not initialize class java.net.NetworkInterface -

-

i have emr setup, supposed come hive , hadoop pre-configured.

as far, can see command require mapreduce job, hive fails.

failed: execution error, return code 2 org.apache.hadoop.hive.ql.exec.mr.mapredtask

so, went job tracking url, , here relevant output:

diagnostics: not initialize class java.net.networkinterface java.lang.noclassdeffounderror: not initialize class java.net.networkinterface @ org.apache.hadoop.net.netutils.islocaladdress(netutils.java:690) ...

any error appreciated...

stack trace points codes:

org.apache.hadoop.net.netutils

network interface definition

i got exact stacktrace when trying run datanode. ipv4 address of eth0 interface forward-resolvable in dns, wasn't reverse-resolvable (i.e. resolve hostname ip reverse lookup of ip corresponding hostname didn't work). datanode started expected once ptr record pointing ip hostname got created.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
