Hash verification failed for CDH5.8.2 installation

Problem Hash Verification failed
In cdh5.8.2 web interface cluster installation process, Parcels hash check failed.

2. Solution 1(Hoodwink)

1. Modify the hash value of manifest.JSON

[root @ hadoop – 01 parcels] # cat CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel. Sha

227d11e344698c70e654ca6768fc017735b73ae3

[root @ hadoop – 01 parcels] # sha1sum CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel

cb7c70d07e68a256a1cb3b06e79e688ac64f3432 CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel

[root @ hadoop – 01 parcels] # cat manifest. Json | grep CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel

“ParcelName” : “CDH – 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel”,
 

[root @ hadoop – 01 parcels] # vi manifest. The json

# by/into the search mode, the input CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel,
the hash from 227 d11e344698c70e654ca6768fc017735b73ae3 instead of cb7c70d07e68a256a1cb3b06e79e688ac64f3432

2. In the Web interface, click Back, and then click Continue

Iii. Solution 2(Root cause)

If solution 1 , still can’t solve, may parcel file damage.

so you need to download, then web interface don’t shut down, click Back , click Continue .

Delete the local CDH-5.8.2-1.CDH5.8.2.p0.3-el6.Parcel file

[root @ hadoop – 01 parcels] # rm -f CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel
2. Redownload

[root @ hadoop – 01 parcels] # wget HTTP:// http://archive.cloudera.com/cdh5/parcels/5.8.2/CDH-5.8.2-1.cdh5.8.2.p0.3-el6.parcel
3. Check the hash value again for comparison

[root @ hadoop – 01 parcels] # sha1sum CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel

227 d11e344698c70e654ca6768fc017735b73ae3 CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel

[root @ hadoop – 01 parcels] #
[root @ hadoop – 01 parcels] # cat CDH 5.8.2-1. Cdh5.8.2. P0.3 – el6. Parcel. Sha

227d11e344698c70e654ca6768fc017735b73ae3
 
### # consistent, that means the download file is complete, not damaged
4. In the Web interface, click Back and then click Continue to find the error

5. In the Web interface, click Back quickly and decisively

 

6. To each machine manually delete the folder/opt/cloudera/parcels /. Flood and restart the agent

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# rm -rf /opt/cloudera/parcels/.flood

[[email protected] ~]# service cloudera-scm-agent restart

[[email protected] ~]# service cloudera-scm-agent restart

[[email protected] ~]# service cloudera-scm-agent restart

[[email protected] ~]# service cloudera-scm-agent restart

[[email protected] ~]# service cloudera-scm-agent restart

[root-Hadoop-06 ~]# Service Cloudera-SCM-Agent Restart
7. In the Web interface, click Continue again and find the following error

?Untar failed with return code: 2, with tar output: stdout: [], stderr: [ gzip: stdin: invalid compressed data–crc error tar: Child returned status 1 tar: Error is not recoverable: No coinages now] -Hadoop-04

8. Google, cloudera community search, unable to resolve

9. Perform step 6 again

Close the current page, open http://172.16.101.54:7180

11. Click Add Cloudera Management Service to create CMS Service

12. Click Add Cluster, create Cluster, failed, cannot click Continue, should be a bug

13. Force uninstall and clean the cluster’s files and install packages

14. Reinstall, the interface is as follows

 

Iv. Lessons learned:

A. Verify downloaded files

B When Hash Verification failed occurs, do not do solution 1, go to Solution 2 step 1-3, then click back and continue button

C. Simply follow steps 13-14 of Solution 2
 

 
5. Note
Encounter the problem, fight it, exhaust methods, improve yourself, start again.
