emr cluster node down - unable to access hive tables










0















I am running my spark job on Emr cluster and I have been using Hive Tables as my data source which uses hdfs:///home/hadoop/database directory as target-dir for my database directory.



When I ran my spark job, it lost a cluster node and it came back up after sometime.



Now I am trying to run my read my Hive Tables and it throws Could not obtain block.



Is it because the particular table is stored in the node (The node that sometimes down) ?



When a EMR cluster node is down, will it restart and have none of the previous HDFS data stored?






scala apache-spark hadoop hive apache-spark-sql

          0 I'm wondering if I can run a Node.js script in my Jekyll page from GitHub Pages or Amazon S3? I think it can't run on GitHub Pages since it doesn't support server side code. Not too sure. The code is below: var Airtable = require('airtable'); var base = new Airtable(apiKey: 'YOUR_API_KEY').base('appAnZVyYqusNPV5Q'); base('Invitee list').select( // Selecting the first 3 records in Complete list: maxRecords: 3, view: "Complete list" ).eachPage(function page(records, fetchNextPage) // This function (`page`) will get called for each page of records. records.forEach(function(record) console.log('Retrieved', record.get('Email')); ); // To fetch the next page of records, call `fetchNextPage`. // If there are more records, `page` will get called again. // If there are no more records, `done` will get called. fetchNextPage(); , function done(err) if (err) console.error(err); return; ); node.js ...
