我正在使用IBM沙盒的hortonworks在hive中执行更新。
我创建了具有ACID属性的表，并且还创建了表。
然后我做了set hive.txn.manager。
然后我收到以下消息：
FAILED: Semantic Exception [Error 10294]: Attempt to do update or delete using transaction manager that does not support these operations,while doing update.
请建议更新配置单元中的行的方法。

在CLI中设置 var isDevBuild = process.argv.indexOf('--env.prod') < 0;
var path = require('path');
var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var extractCSS = new ExtractTextPlugin('vendor.css');
module.exports = (env) => {
return [{
stats: { modules: false },
resolve: {
extensions: ['.js']
},
module: {
rules: [{
test: require.resolve('jquery'),
use: [{
loader: 'expose-loader',
options: 'jQuery'
},{
loader: 'expose-loader',
options: '$'
}]
}],
loaders: [
{ test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, loader: 'url-loader?limit=100000' },
{ test: /\.css(\?|$)/, loader: extractCSS.extract(['css-loader']) }
]
},
entry: {
vendor: [
'aurelia-event-aggregator',
'aurelia-fetch-client',
'aurelia-framework',
'aurelia-history-browser',
'aurelia-logging-console',
'aurelia-pal-browser',
'aurelia-polyfills',
'aurelia-route-recognizer',

'aurelia-templating-binding',
'aurelia-templating-resources',
'aurelia-templating-router',
'bootstrap',
'bootstrap/dist/css/bootstrap.css',
'jquery',
'noty'
],
},
output: {
path: path.join(__dirname, 'wwwroot', 'dist'),
publicPath: '/dist/',
filename: '[name].js',
library: '[name]_[hash]',
},
plugins: [
extractCSS,
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable)
new webpack.DllPlugin({
path: path.join(__dirname, 'wwwroot', 'dist', '[name]-manifest.json'),
name: '[name]_[hash]'
})
].concat(isDevBuild ? [] : [
new webpack.optimize.UglifyJsPlugin({ compress: { warnings: false } })
])
}];
}
并不总是有效。
在hive-site.xml中设置此选项并重新启动
set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager
set hive.compactor.initiator.on=true;
ACID需要这些属性。
还要确保您的表格的属性设置为set hive.compactor.worker.threads=1;
