Hello,
I have a problem with TOS Big Data v6, i try to read a file located int the hdfs with a tHDFSInput and a have this error :

My configuration :
Windows 7 machine
TOS Big Data v6 (installed in local machine)
VM Clouera 5.4.2
I already install the hadoop bin module (v2.6) and create the environement var HADOOP_HOME.
Thanks for your help.
Hi sabrina, I'm able to access to hdfs from my local machine. Actually, i already configurated the hadoop cluster in Talend repository. I able to retrive the files from the cluster, but when i tried to use the tHDFSInput to read the file, i got this message :
Exception in component tHDFSInput_1 org.apache.hadoop.hdfs.BlockMissingException: Could not obtain block: BP-286282631-127.0.0.1-1433865208026:blk_1073742440_1620 file=/user/hdfs/achats.txt at org.apache.hadoop.hdfs.DFSInputStream.chooseDataNode(DFSInputStream.java:938) at org.apache.hadoop.hdfs.DFSInputStream.blockSeekTo(DFSInputStream.java:607) at org.apache.hadoop.hdfs.DFSInputStream.readWithStrategy(DFSInputStream.java:847) at org.apache.hadoop.hdfs.DFSInputStream.read(DFSInputStream.java:897) at java.io.DataInputStream.read(DataInputStream.java:149) at java.io.FilterInputStream.read(FilterInputStream.java:133) at java.io.PushbackInputStream.read(PushbackInputStream.java:186) at org.talend.fileprocess.UnicodeReader.<init>(UnicodeReader.java:25) at org.talend.fileprocess.TOSDelimitedReader.<init>(TOSDelimitedReader.java:77) at org.talend.fileprocess.FileInputDelimited.<init>(FileInputDelimited.java:93) at local_project.tes_001_0_1.tes_001.tHDFSInput_1Process(tes_001.java:741) at local_project.tes_001_0_1.tes_001.runJobInTOS(tes_001.java:1136)
