unable to connect hadoop using Talend Bigdata

[Anonymous]

Hi,

I have installed Hadoop in windows machine and tried to connect from Talend big data open studio, but I am unable to connect.

I am getting 'Compilation' error as follows.

Is it related to any jar files to be downloaded??

I am unable to download some optional packages, it is failing and tried multiple times.

@Vibin_CT,can you check the required jars are installed in your talend setup? in Module section you will find the all jars.

Hello,

Does the issue 'apache-curator' block you to use TOS-BD? It is not necessary to download all optional modules before using TOS-BD. The required jars will be pop-up again as a download/install dialog when you need to use some detailed function.

Here exists a jira issue about:

https://jira.talendforge.org/browse/TUP-20803

Hi @manodwhb,

Could you please specify where exactly I can see installed jars in Talend?

Hi @xdshi,

Thanks for the information. I think 'Apache-curator' is blocking other jars to download.

But I am unable to see any jars needed for tHDFSConnection component for 'Custom-Unsupported' Distribution option.

Hello,

Did you follow up this online document about:TalendHelpCenter:Connecting to a custom Hadoop distribution to connect hadoop distribution 2.7.7?

Have you tried to connect hadoop with supported distribution by talend(2.5, 2.6) to see if it works?

Best regards

Hi @xdshi,

I tried for the custom distribution also, but still it is asking some libraries to download and unable to download.

At last I have installed Cloudera in VMware and tried same distribution in Talend. Now I am not getting any compile time error. It seems the issue is with custom distribution.

Thanks for your feedback. Is the connection hadoop 2.7.7 OK with you?

Hi @xdshi,

Yes. Now I am able to connect Hadoop (Cloudera VMware) using Talend Big Data. Appreciate your valuable comments.
